FCC ID: K95APV5 SECTION 6 DETAILED RF TECHNICAL INFORMATION FCC ID: K95APV5 Theory of Operation Equipment Description The APV series radios are portable (handheld) VHF transceivers operating in the 136 to 174 MHz band using frequency modulation. The units are designed for use in the Land Mobile Services, both domestic and foreign. They are multi-channel digitally synthesized radios using a single temperature compensated crystal oscillator. Usable channels are dealer programmable from 136 to 174 MHz in 2.5 kHz increments. The radios are available in a sixteen-channel configuration (APV5016) with a single bank or group and in larger configurations (APV5240) using multiple banks. Channel frequency information is stored in an EEPROM with up to 15 banks of channels available to yield a capability of up to 240 channels. The APV5240 is comprised of a main printed circuit board (PCB) assembly and a front panel display printed circuit board assembly, and the APV5016 is only comprised of a main board assembly. The main PCB consists of the micro-controller, EEPROM, transmitter, receiver, and audio circuits. The EEPROM is used to store frequencies, configurations, and other user specific information. The front panel assembly of the keyboard/display model consists of the LCD display, display controller circuit, and keypad. Main PCB Assembly Microprocessor Control The Microprocessor (U12) controls the radio functions such as loading the synthesizer, detecting the keyboard and various switch modes, adjusting the transmitter and receiver circuit tuning drivers, and generating and detecting the various signaling formats. Regulation The 6V switching power supply U14 supplies voltage to U11 (5-Volt regulator), U13 (5-Volt regulator), U16 (5-Volt regulator), U27 (5-Volt regulator), U17 and U18 (IF analog switches), and to U15 (Sub-IF IC). U11 supplies 5 volts to U12 (Microprocessor), U4 (D/A converter), U8 (EEPROM) and to all the controlling and logic switching circuits. U13 supplies 5 volts to the various RX audio circuits such as U1 (Audio LSI), U7 (DTMF Receiver), and the various op amps associated with these circuits. U16 supplies 5 volts to Q13 (IF amplifier) and to U19 (pre-selector tuners). U27 supplies 5 volts to G1 (TCXO), U21 (Synthesizer ASIC), U29 (Phase Detector), U30 (Loop Filter) and, U31 (Pre-scalar). FCC ID: K95APV5 Synthesizer U21 is a 44pin QFP Synthesizer ASIC IC. It provides highly stable, low noise, frequency source for 2.5 kHz, 5 kHz, and 6.25 kHz channel spacing resolution. The ASIC includes a Reference Divider, Phase Accumulator, Digital Compensation, Phase Detector, and CPU interface and decoder. The synthesizer is a Fractional-N type based on the 3 rd order loop of the ASIC design. The phase detector including U28 provides a DC voltage that is proportional to the phase error between the divided down frequency from the ASIC and the divided down carrier frequency. This voltage is fed to the loop filter and then to the VCO. This error correction voltage causes the VCO frequency adjustment in a direction to maintain phase lock between the divided down frequency. The synthesizer employs a two-point modulation scheme. One modulation point leads to the VCO and the other point leads to the phase detector. The phase detector modulation point allows true data to be modulated. TCXO The hybrid 12.8 MHz temperature compensated crystal oscillator (G1) is fed into he ASIC as the reference oscillator for all frequency synthesis. The hybrid design with temperature compensations provides less than +/- 2.5ppm of drift between -30°C and +60°C. The ASIC divides the reference into other external references such as 8 MHz for U12 (Microprocessor), 320 kHZ/349 kHz for U14 (Switching Regulator). Prescaler The “dual modulus” prescaler U31 is the frequency divider in the feedback path of the synthesizer. Loop Filter The loop filter including U30 removes noise and unwanted frequency components from the output of the phase detector (U29). The synthesizer employs a multiple filter bandwidth design, thus, optimizing the filter response during steady state or scanning modes. VCO Q27 and Q28 are the TX/RX VCO’s. They are configured as a Colpitts, low phase noise type oscillators. Each VCO has a Coarse and Fine voltage tune line leading in from the synthesizer to varactors diodes CR41-48. VCO selection is through PUMX transistors Q25 and Q26. The transmitter audio is fed to CR67 and CR40 for VCO modulation. FCC ID: K95APV5 Receiver Section The receive signal from the antenna connector is fed through the harmonic filter and split from the TX path to the RF amplifier (Q12) and pre-selectors. “Tuner” voltage amplifiers of U19 tune the pre-selector varactors CR18-CR33 for the desired selectivity. The RF signal is then mixed with the RX LO drive signal from the VCO. The major components of the active mixer consist of T1, T2, and Q14-17. From the mixer, the 16.9 MHz “resulting” IF frequency is filtered through FL1 a 4-pole crystal filter. The IF signal is then amplified by Q13 and fed into the 2 nd mixer input of U15 of the sub-IF IC. U15 includes the 2 nd mixer, 2 nd IF amp, “Limiter”, and “Quadrature”. The 16.445 MHz 2 nd LO crystal Y2 is connected to the oscillator input/output for 2 nd LO mixing. Ceramic filters FL3, FL4, FL8, and FL9 provide 2nd IF wide and narrow band filtering through the respective ports of U15. The discriminated audio output from pin 8 is split off into two circuit directions. One path delivers a discriminator voltage used for calibration and the other path leads to audio processing circuits and to U1 the Audio LSI IC. Audio The receiver audio from the discriminator is split again and filtered before being processed in the Audio LSI IC. One path (voice) is connected to a 300Hz high pass filters including U5 and U10 before the LSI processing. The other path (sub-audio) is connected to a 250 Hz sub LPF including U5 to pass the sub-audio tones to the DC restoration circuit including U34 and CR2-3. …
