21、 transmitting, FM mode operates in a double con-version and other modes (AM, SSB, CW, FSK) operate in a triple conversion.While receiving, the fi rst IF operates in 73.095MHz triple conversion.

This 15.6MHz signal passes through a buffer (Q502) and is doubled in a multiplier (Q503) t

25、o generate a 31.2MHz signal. The 31.2MHz signal is used as a reference signal for LO3 (the third local oscillator) DDS (IC601). The 31.2MHz signal is doubled in multipliers (Q504, Q505) to generate a 62.4MHz signal. The 62.4MHz signal is used as a reference signal for LO1 (the fi rst local oscillato

26、r) PLL (IC801).The SO-3 (TCXO unit: 15.6MHz) is confi gured as an op-tion in this transceiver, so that you can replace the crystal oscillation circuit (X502, Q501) with the SO-3. When using the SO-3, remove the CN903 and CN904 short jumper wires in order to stop the operation of the crystal oscillat

27、ion circuit (X502, Q501).LO1/ LO2/ LO3 LO1 (the fi rst local oscillator)The VCO (Q806) oscillates at 196.8MHz. Only the double frequency component, 393.6MHz, of this VCOs oscilla-tion output is extracted and input into PLL (IC801) pin 6. This input signal is divided into 1/N within the PLL. Also, th

28、e 62.4MHz signal (15.6MHz reference frequency x 4) is input into PLL pin 8 and divided into 1/R within the PLL. By a phase comparator in the PLL, the frequency divided into 1/N and the frequency divided into 1/R are compared, and then the frequency is locked. The comparison frequency (f) at this tim

29、e is 120kHz when transmitting FM, and 2.4MHz otherwise.393.6MHz signal locked by PLL (IC801) would be used as reference by DDS (IC803). The output signal from DDS (IC803) is 12.495MHz to 32.195MHz when RX-1 path is selected, amplified at the broad band amplifier (IC804), TS-590S6and then goes throug

30、h BPF and is output as LO1. When RX-2 path is selected or when transmitting, 36.5625MHz to 66.5475MHz is output, amplifi ed by the broad band ampli-fi er (IC804), and then doubled in the multiplier (D652), goes through BPF, and is output as 73.120MHz to 133.095MHz LO1. LO2 (the second local oscillat

31、or)The reference oscillating circuits output signal 15.6MHz signal passes through a buffer (Q502) and is doubled in a multiplier (Q503) to generate a 31.2MHz signal. The 31.2MHz signal is also used as the DDS (IC601)s reference Fig. 2 Reference signal generator, LO1/ LO2/ LO3frequency, and therefore

32、 its resistance is divided. Then, the 31.2MHz signal is doubled in multipliers (Q504, Q505) to generate a 62.4MHz signal.The 62.4MHz signals high harmonic is cut in the BPF and the signal is amplifi ed in the amplifi er (Q506) to gener-ate LO2. If IFB is selected, the diode switch (D501) cuts the LO
