15、 Note: 7FTM-10R/E Technical Supplement Circuit Description RECEPTION VHF Reception The incoming VHF signal is passed through the low-pass filter network, antenna switching diodes and low-pass fil- ter network to the RF amplifier Q1009 (3SK296ZQ). The amplified RF signal is passed through the band-pa

16、ss fil- ter again by varactor-tuned resonators L1024, L1025, and D1026 (HVC365) then applied to the 1st mixer Q1010 (3SK296ZQ) along with the first local oscillator signal from the PLL circuit. The first local oscillator signal, between 191.25 MHz and 195.25 MHz, is generated by the VHF VCO, which c

17、on- sists of Q1309 (2SC5006) and varactor diodes D1310 (HVC365), D1311 (HSC277TRF), and D1312 (HVC365), according to the receiving frequency. UHF Reception The incoming UHF signal is passed through the low-pass filter network, antenna switching diodes and Low-pass filter network to the RF amplifier

18、Q1011 (3SK296ZQ). The amplified RF signal is passed through the band-pass fil- ter varactor-tuned resonators D1031 and D1032, and D1033 (all HVC350B) then applied to the 1st mixer Q1013 (3SK296ZQ) along with the first local signal from the PLL circuit. The first local oscillator signal is generated

19、between 382.75 MHz and 402.75 MHz by the UHF VCO, which consists of Q1313 (3SK296ZQ) and varactor diodes D1314 (HSC277TRF), D1315 and D1316 (both HVC375B), ac- cording to the receiving frequency. IF and Audio Circuits The 47.25 MHz first IF signal is applied to the monolithic crystal filters XF1401

20、and XF1402 which strip away un- wanted mixer products, and the IF signal is applied to the first IF amplifier Q1407 (2SC4915). The amplified first IF signal is then delivered to the FM IF subsystem IC Q1408 (NJM2552V-TE1), which contains the second mix- er, limiter amplifier, noise amplifier, and FM

21、 detector. The second local oscillator signal is generated by the 46.8 MHz crystal X1301 and Q1403 (2SC4915), produces the 450 KHz second IF signal when mixed with the first IF signal within Q1408 (NJM2552V-TE1) it produces the 450 KHz second IF signal. The 450 KHz second IF signal is applied to the

22、 ceramic filter CF1402, which strips away unwanted mixer prod- ucts. The limiter amplifier within Q1408 (NJM2552V-TE1) removes the amplitude variations of the 450 KHz IF sig- nal. Speech detection is within Q1408 and the ceramic discriminator CD1401. The detected audio passes through the de-emphasis

23、 net- work, a low-pass filter consisting of Q1419 (LM2902PWR) and associated circuitry, and then a high-pass filter con- sisting of Q1420 (LM2904PWR) and associated circuitry. The filtered audio signal is passed through the audio vol- ume control IC Q1511 (M61524FP-DF0G) that adjusts the audio sensi

24、tivity to compensate for audio level variations. When the internal speaker is selected, the audio signal is amplified by Q1602 (TDA1519CTH) then applied to the internal loudspeaker. When the external speaker is select- ed, the audio signal is amplified by Q1602 (TDA1519CTH), and then passed through

25、the EXT SP jack to the external loudspeaker. Transmit Signal Path The speech signal from the microphone passes through the MIC jack J1604 to AF amplifier Q1508 (LM2904PWR) on the MAIN unit. The amplified speech signal ampli- tude is limited by Q1509 (M62429FP 780C). The speech signal passes through

26、buffer amplifier Q1501 (LM2902PWR) and the low-pass filter network section of Q1501 (LM2902PWR). VHF Transmit Signal Path The adjusted speech signal from Q1501 (LM2902PWR) frequency modulates the VHF transmitting VCO, made up of Q1309 (2SC5006) and D1312 (HVC350B). The modulated transmit signal pass

27、es through buffer amplifier Q1308, and Q1307 (both HSC277TRF). The filtered transmit signal is applied to the Pre-Drive amplifier Q1003 (2SK2596BXTL) and Drive amplifier Q1002 (RD07MVS1), and then is finally amplified by Pow- er amplifier Q1001 (RD70HVF1) up to 50 Watts. This three stage power ampli

28、fiers gain is controlled by the APC cir- cuit. The 50 Watt RF signal passes through the high-pass filter and low-pass filter networks, the antenna switch D1007 and D1008 (both L709CER), and another low-pass filter network, The signal is then delivered to the ANT jack. UHF Transmit Signal Path The ad

29、justed speech signal from Q1501 (LM2902PWR) frequency modulates the UHF transmitting VFO, made up of Q1313 (2SC5006-T1) and D1316 (HVC375B). The modulated transmit signal passes through buffer amplifier Q1312, Q1310 and Q1311 (all 2SC5006). The filtered transmit signal is applied to the Pre-Drive am

30、plifier Q1003 (2SK2596BXTL) and Drive amplifier Q1002 (RD07MVS1), and then finally is amplified by Pow- er amplifier Q1001 (RD70HVF1) up to 40 Watts. This three 8FTM-10R/E Technical Supplement Circuit Description stage power amplifiers gain is controlled by the APC cir- cuit. The 40-Watts RF signal

31、passes through the high-pass fil- ter and low-pass filter networks, antenna switch D1014 (L709CER), another low-pass filter network, and then is delivered to the ANT jack. Transmit APC Circuit A portion of the Power amplifier output is rectified by D1009 and D1010 (UHF: D1037 and D1038) (both MA2S72

32、800L), then delivered to APC Q1317 (LM2904PWR), as a DC voltage which is proportional to the output level of the power amplifier. The APC Q1317 (LM2904PWR) is the rectified DC volt- age from the power amplifier and the reference voltage from the main CPU Q1813 (HD64F2266TF13), to produce a control v

33、oltage, which regulates the supply voltage to the Pre-Drive amplifier Q1003 (2SK2596BXTL), Drive amplifier Q1002 (RD07MVS1-T12) and Power amplifier Q1001 (RD70HVF1), so as to maintain stable output power under varying antenna loading condition. PLL A portion of the output from the VCO Q1309 (2SC5006

34、- T1), or Q1313 (2SC5006-T1) passes through the program- mable divider section of the PLL IC Q1304 (MB15A02PFV1-G-BND-EFE1), which divides it accord- ing to the frequency data that is input from the main CPU Q1813 (HD64F2266TF13). It is then sent to the phase com- parator. The 11.7 MHz frequency of

35、the reference oscillator circuit made up of X1301 is divided by the reference frequency divider section of Q1304 (MB15A02PFV1-G-BND-EFE1) into 4250 or 3400 parts to become the 5 kHz or 6.25 kHz comparative reference frequencies, which are utilized by the phase comparator. The phase comparator sectio

36、n of Q1304 (MB15A02PFV1- G-BND-EFE1) compares the phase between the frequen- cy-divided oscillation frequency of the VCO circuit, and the comparative frequency. The output is a pulse corre- sponding to the phase difference. This pulse is integrated by the charge pump and loop filter of Q1304 (MB15A0

37、2PFV1-G-BND-EFE1) into a control voltage (VCV) to control the oscillation frequency of the VCOs. 9FTM-10R/E Technical Supplement The FTM-10R/E has been carefully aligned at the fac- tory for the specified performance across the 144 MHz and 430 MHz amateur bands. Realignment should there- fore not be

38、 necessary except in the event of a component failure. All component replacement and service should be performed only by an authorized Yaesu representa- tive, or the warranty policy may be void. The following procedures cover adjustments that are not normally required once the transceiver has left t

39、he factory. However, if damage occurs and some parts are subsequently replaced, realignment may be required. If a sudden problem occurs during normal operation, it is like- ly due to component failure. Realignment should not be done until after the faulty component has been replaced. We recommend th

40、at servicing be performed only by authorized Yaesu service technicians, who are experienced with the circuitry and fully equipped for repair and align- ment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instruc- tions regarding repair. Authorized

41、 Yaesu service techni- cians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unau- t

42、horized attempts at realignment are not covered by the warranty policy. Yaesu must reserve the right to change circuits and alignment procedures in the interest of im- proved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function an

43、d operation of the transceiver is clearly understood, the cause of the malfunction has been clearly pinpointed, any faulty components replaced, and the need for realignment is determined to be absolutely necessary. Required Test Equipment The following test equipment (and familiarity with its use) i

44、s necessary for complete realignment. Correction of prob- lems caused by misalignment resulting from use of im- proper test equipment is not covered under the warranty policy. While most steps do not require all of the equip- ment listed, the interactions of some adjustments may require that additio

45、nal adjustments be performed. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented. RF Signal Generator with calibrated output leve

After complet- ing one step, read the following step to determine wheth- er the same test equipment will be required. If not, re- move the test equipment (except dummy load and watt- meter, if connected) before p

49、roceeding. Correct alignment requires that the ambient temperature of the transceiver be the same as that of the test equip- ment, and that the temperature be held constant between 20 and 30 C (68 86 F). When the transceiver is brought into the shop from hot or cold air it should be allowed some time for thermal equalization with the environment before alignment. If pos
