circuit description 1) receiver system the receiver system is a double superheterod yne system with a 21. 7mhz first if and a 450khz second if. 1.front end the received signal at frequency in the 136~173.995mhz (e version: 144~145.995mhz) range is passed throug h the low-pass filter (l101, l102, l104, l118, c101, 108, c109, c110, c1 17, c118, c119, c123, c124, c125, c126, c127, and c188) and tuning circ uit (c255, c256, c257, c258, d120, l138, and l139) and amplified by the rf amplifier (q119). the signal from q119 is then passed through the tuni ng circuit (c242, c243, c244, c245, c269, c270, c271, d117, d118, d1 19, l135, l136, and l137) and converted into 21.7mhz by the mixer (q118). the tuning circuit, which c onsists of l139, l135, l136, varicaps d117, d118, d119, and d120 is controlled by the tracki ng voltage from the cpu so that it is optimized for the recepti on frequency. the local signal from the vco is passed through the buffer (q115), and supp lied to the source of the mixer (q118). the radio uses the lower side of the superheterodyne system. 2. if circuit the mixer mixes the received signal with the local signal to obtain the sum of and difference between them. the crysta l filter (fl101, and fl102) selects 21.7mhz frequency from the results and e liminates the signal of the unwanted frequencies. the first if amplifier (q 121) then amplifies the signal of the selected frequency. 3. demodulator circuit after the signal is amplified by the first if amplifier (q121), it is input to pin 16 of the demodulator ic (ic103). the se cond local signal of 21.25mhz (shared with pll ic reference oscillation), wh ich is oscillated by the tcxo (x102). then, these two signals are mixed by the internal mixer in ic103 and the result is converted into the second if signal with a frequency of 450khz. the second if signal is output from pin 3 of ic103 to the ceramic filter (fl103), where the unwanted frequency band of that signal is eliminated, and the resulting signal is sent back to the ic103 through pin 5. the second if signal input via pin 5 is demodulated by the internal limiter amplifier and quadrature detection circui t in ic103, and output as an audio signal through pin 9. http://www..net/ datasheet pdf - http://www..net/
4. audio circuit the audio signal from pin 9 of ic103 is amplified by the af amplifier (q120). the signal is then input to pin 16 of t he electronic volume (ic105) for volume adjustment, and output from pin 14. t he adjusted signal is sent to the audio power amplifier (ic104) through pin 2 to drive the speaker. 5. squelch circuit the signal except for the noise component in af signal of ic103 is cut by the active filter inside ic. the noise com ponent is amplified and rectified, then converted to the dc voltage to output fr om pin 14 of ic103. the voltage is led to pin 2 of cpu and compared with the setting voltage. the squelch will open if the input voltage is lower than the setting voltage. 2) transmitter system 1. modulator circuit the audio signal is converted to an electric signal in either the internal or external microphone, and input to the microphone amplifier (ic110). ic110 consists of two operational amplifiers ; one amplifier (pins 12, 13, and 14) is composed of pre-emphasis and idc circuits and the other (pins 5, 6, 7, 8, 9, and 10) is composed of a splatter filter . the maximum frequency deviation is obtained by ic105 and input to the cat hode of the varicap of the vco, to change the electric capacity in the o scillation circuit. this produces the frequency modulation. 2. power amplifier circuit the transmitted signal is oscillated by the vco, amplified by the pre-drive amplifier (q101) and drive amplifier (q106 ), and input to the final amplifier (q105). the signal is then amplified by the final amplifier (q105) and led to the antenna switch (d101) and low-pass filter (l104, l102, l101, c119, c118, c117, c127, c126, c125, c124, c108, and c101), where un-wanted high harmonic waves are reduced as needed, and the resulting signal is supplied to the antenna. 3. apc circuit part of the transmission power from the low-pass filter is detected by d108, converted to dc, and then amplified by a amplifier (ic101). the output voltage controls the bias voltage from the so urce of q105 and q106 to maintain the transmission power constant. http://www..net/ datasheet pdf - http://www..net/
3) pll synthesizer system 1. pll the dividing ratio is obtained by sending data from the cpu (ic113) to pin 10 and sending clock pulse to pin 9 of the pll ic ( ic101 ). the oscillated signal from the vco is amplified by the buffe r (q116) and input to pin 8 of ic102. each programmable divider in ic102 divi des the frequency of the input signal by n according to the frequency data, to generate a comparison frequency of 5 or 6.25khz. 2. reference frequency circuit the reference frequency appropriate for the channel steps is obtained by dividing the 21.25mhz reference o scillation (x102) by 4250 or 3400, according to the data from the cpu (i c113). when the resulting frequency is 5khz, channel steps of 5, 10, 15, 20, and 30khz are used. w hen it is 6.25khz, channel steps of 12.5, 25 , and 50khz are used. 3. phase comparator circuit the pll (ic102) uses the referenc e frequency, 5 or 6.25khz. the phase comparator in the ic102 compares the phase of the frequency from the vco with that of the comparison frequency, 5 or 6.25khz, which is obtained by the internal divider in ic102. 4. pll loop filter circuit if a phase difference is found in the ph ase comparison between the reference frequency and vco output frequency, the c harge pump output (pin 5) of ic102 generates a pulse signal, which is converted to dc voltage by the pll loop filter and input to the va ricap of the vco unit for oscillation frequency control. 5. vco circuit a colpitts oscillation circuit driven by q108 directly oscillates the desires frequency. the frequency control voltage determined in the cpu (ic113) and pll circuit is input to the varicaps (d105 and d107). this change the oscillation frequency, which is amplifi ed by the vco buffer (q113) and output from the vco unit. http://www..net/ datasheet pdf - http://www..net/
4) cpu and peripheral circuits 1. lcd display circuit the cpu turns on the lcd via segment and common terminals with 1/4 the duty and 1/3 the bias, at the frame frequency is 112.5hz. 2. display lamp circuit when the lamp key is pressed, ?l? is output form pin 67 of cpu ( ic113) to the bases of q140. q140 then turn on and the leds (d128 and d129) light. 3. reset and backup when the power form the dc jack or external battery increases from circuits 0v to 2.5 or more, ? h ? level reset signal is output form the reset ic (ic108) to pin 6 of the cpu (ic113), causing the cpu to reset. the reset signal, however, waits at 100, and does not enter the cpu until the cpu clock (x104) has stabilized. 4. s (signal) meter circuit the dc potential of pin 12 of ic103 is input to pin 83 of the cpu (ic113), converted from an analog to a digital signal, and displayed as the s-meter signal on the lcd. 5. dtmf encoder the cpu (ic113) is equipped with an internal dtmf encoder. the dtmf signal is output from pin 71, through ic 112 (low-pass filter), and then through the microphone amplifier (ic110), and is sent to the varicap of the vco for modulation. at the same time, the monitoring tone passes through the af circuit and is output form the speaker . 6. tone encoder the cpu (ic113) is equipped with an in ternal tone encoder. the tone signal (67.0 to 250.3hz ) is output from pin 70 of the cpu to t he 21.25mhz reference oscillation (x102) of the pl l reference oscillator. 7. dcs encoder the cpu (ic113) is equipped with an internal dcs code encoder. the code (023 to 754) is output from pin 70 of the cpu to the 21.25mhz reference oscillation (x102) of the pl l reference oscillator. http://www..net/ datasheet pdf - http://www..net/
8. ctcss, dcs decoder the voice band of the af out put signal from pin 9 of ic103 is cut by sharp active filter ic111 and amplif ied, then led to pin 80 of cpu. the input signal is compared with the programmed tone frequ ency code in the cp u. the squelch will open when they match. 9. clock shift in the unlikely event that cpu clock noise is present on a particular operating frequency programmed into the radio, you can shift the cpu clock frequency to avoid the cpu clock-noise. the output signal from pin 8 of the cpu turns on q127. then the oscillation frequency of x104 will be shifted about 200 ppm. http://www..net/ datasheet pdf - http://www..net/
