1、S-15008XZ-C1 July 2013 HF/VHF/UHF ALL MODE TRANSCEIVER This service manual describes the latest technical information for the IC-7100 HF/VHF/UHF ALL MODE TRANSCEIVER, at the time of publication. NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than the specifi ed

27、nds The RX signal from the antenna connector (ANT1: J1) is passed through the power/SWR detect circuit (D961 and D962) and one of the LPFs, depending on the operating band, to remove unwanted out-of-band signals. (See the LPF TABLE below.) The fi ltered RX signal is passed through the TX/RX SW (RL80

28、1) and LPF (L801, L802, C801, C803 and C805) for fur- ther removal of unwanted signals, and then passed through the mute SWs (D181 and D182). When the attenuator is turned ON, the RX signal is passed through the 18 dB attenuator (MAIN UNIT: D3082 and D3083). The RF signal is passed through one of th

29、e BPFs, depend- ing on the operating frequency, to remove unwanted signals. (See the BPF TABLE on page 3-2.) The fi ltered signal is applied to the pre-AMP circuit. PRE-AMP CIRCUIT (MAIN UNIT) When the pre-AMP is turned ON, the RX signal is amplifi ed by the pre-AMP (Q3201). The amplifi ed signal is

30、 applied to the 1st RX IF circuits.

36、NT2) is passed through the power/SWR detect circuit (D651 and D661) and LPF (L591 to L593, C591 and C592). 144 MHz BAND SIGNAL The RX signal is passed through the LPF (L541 to L543, C542 to C547) and TX/RX SW (RL531). When the attenuator is turned ON, the RX signal is also passed through the 20 dB a

When the attenuator is turned ON, the RX signal

39、 is also passed through the 18 dB attenuator (D451 and D452). The RX signal is then passed through the BPF (MAIN UNIT : D454, L452 and C454) and applied to the pre-AMP (Q451). The amplifi ed signal is passed through the 2-staged BPF (MAIN UNIT: D455, L453, C468 and D456, L454, C473), and applied to
