SECTION 4 CIRCUIT DESCRIPTION The filtered signals from the bandpass filter are mixed with 1st LO signals at the mixer circuit (Q511, Q512) to produce a 1st IF signal (10.85 MHz [Main] or 10.95 MHz [Sub]). The 1st LO signals (125.15 MHz–163.15 MHz) are PLL output frequency, which comes from the VHF VCO circuit (PLL unit; Q191, D191–D194).
4-1-6 10 MHz IF CIRCUIT (MAIN UNIT) 4-1-9 SQUELCH CIRCUIT (MAIN UNIT) The 10 MHz IF signal from the mixer circuit is passed through a monolithic filter (Fl51 [Main], Fl651 [Sub]) to suppress out-of-band signals. The filtered signal is amplified at the IF amplifier (Q51 [Main], Q651 [Sub]). The IF amplifier provides 20 dB gain. (1) FM mode A squelch circuit cuts out AF signals when no RF signal is received or the S-meter signal is lower than the [SQL] control setting level.
4-1-11 NOISE BLANKER CIRCUIT (MAIN UNIT) 4-1-13 S-METER CIRCUIT (MAIN UNIT) The noise blanker circuit detects pulse-type noises, and stops IF amplifier operation during detection. The S-meter circuit indicates the relative received signal strength while receiving and changes depending on the received signal strength. A portion of the 10 MHz IF signal from the bandpass filter (FI51 [Main], FI651 [Sub]) is amplified at the noise amplifier circuit (Q102, IC101, Q101 [Main], Q702, IC701, Q701 [Sub]).
While in SSB mode, the amplified signals from the buffer amplifier (Q1651) are then applied to the balanced modulator (IC201). 4-2-4 TRANSMIT IF AMPLIFIER CIRCUIT (MAIN UNIT) The modulated IF signal from a modulation circuit is applied to the IF amplifier circuit (Q1). The amplified IF signal is then applied to the VHF/UHF transmit circuit (PA unit) via the VHF /UHF switching circuit (D52, D53).
low-pass filter and UHF signal are high-pass filter, and then applied to the VHF and UHF power amplifier circuit separately. 4-3 PLL CIRCUITS IC-910H contains 2 PLL circuits and 1 local oscillator. The VHF and UHF PLL circuits adopt “Icom’s original I-loop PLL” to obtain very fast lock up times. 4-2-7 POWER AMPLIFIER CIRCUIT (PA UNIT) The power amplifier circuit amplifies the RF signals to the specified output power.
The passed signals are then applied to the RF amplifier circuit. The amplified signals are passed through the bandpass filter (FI1) to suppress spurious components, and are amplified at the pre-drive amplifier (Q36, Q38) and power module (IC21) to obtain a stable 10 W of output power.
