  • Page 36: Mic And External Mic

    Controller Theory of Operation: TX Audio Circuit 4.2.1 MIC and External MIC The TX audio enters the radio via the internal MIC or the external MIC jack. When using the internal MIC, the audio passes through the external jack then rest of the circuits. When using the external jack, the audio from the internal MIC is cut-off from the rest of the circuits and the external MIC audio is passed to the rest of the circuits.

    136 – 174 MHz VHF Theory of Operation: VHF Transmitter VHF Transmitter The VHF transmitter covers the range of 136 – 174 MHz. Depending on model, the output power of the transmitter is switchable on a per-channel basis between high power (5 Watts) and low power (1 Watt).

  • Page 154: Auto Power Control

    136 – 174 MHz VHF Theory of Operation: VHF Frequency Generation Circuitry 8.3.4 Auto Power Control The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final amp) is sensed across resistor R417. The voltage difference across R417. The differential signal at the output of U401 (pin 7) is passed to Q404 and Q405 that produces a constant power output to the antenna.

    136 – 174 MHz VHF Theory of Operation: VHF Frequency Generation Circuitry 8.4.2 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25 kHz or 5 kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator.

    11-4 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry 11.3.4 Auto Power Control The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final amp) is sensed across resistor R417. The differential signal at the output of U401 (Pin 7) is passed to Q404 and Q405 that produces a constant power output to the antenna.

    403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry 11-5 11.4.2 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25kHz or 5kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator.
