1、S-15005XZ-C1 August 2013 HF TRANSCEIVER This service manual describes the latest technical informa- tion for the IC-F8101/F8100 HF 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 voltage. This will ruin

2、 the transceiver. DO NOT expose the transceiver to rain, snow or liquids. DO NOT reverse the polarities of the power supply when con- necting the transceiver. DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector. This could damage the transceivers front-end. To upgrade qua

3、lity, any electrical or mechanical parts and internal circuits are subject to change without notice or obligation.

ORDERING PARTS 1. Make sure that the problem is internal before dis-assem- bling the transceiver. 2. DO NOT ope

6、n the transceiver until the transceiver is dis- connected from its power source. 3. DO NOT force any of the variable components. Turn them slowly and smoothly. 4. DO NOT short any circuits or electronic parts. An insulated tuning tool MUST be used for all adjustments. 5. DO NOT keep power ON for a l

7、ong time when the trans- ceiver is defective. 6. DO NOT transmit power into a Standard Signal Generator or a Sweep Generator. 7. ALWAYS connect a 40/60 dB attenuator between the trans- ceiver and a Deviation Meter or Spectrum Analyzer, when using such test equipment. 8. READ the instructions of the

8、test equipment thoroughly before connecting it to the transceiver.

36、SW 4-1 RECEIVER CIRCUITS RF CIRCUIT (PA AND MAIN UNITS) The RX signal from the antenna is passed through the SWR detect circuit (PA UNIT; D5001, D5002), TX/RX line SW (PA UNIT; RL5001) and LPF (PA UNIT; L5001, L5002, C5101C5105), and then applied to the MAIN UNIT. The RX signal from the PA UNIT is p

37、assed through or bypassed the attenuator circuit (MAIN UNIT; R1103, R1106, R1108), RX mute SW (MAIN UNIT; Q1101, D1107), TX/RX line SW (MAIN UNIT; D1108), and then applied to the filter circuits. The RX signal is passed through an LPF or one of BPFs, depending on the operating frequency, to remove u

38、nwanted out-of-band signals. The filtered RX signal is applied to or bypassed the preamplifier circuit. The RX signal from the filter circuits is applied to or bypassed the preamplifier. When the Preamplifier function is activated, the RX signal is amplified by the preamplifier (MAIN UNIT; Q1116, Q1

39、117). The amplified or bypassed RX signal is applied to the 1st RX IF circuits. 1ST RX IF CIRCUIT (MAIN UNIT) The RX signal from the preamplifier circuit is applied to the 1st RX IF mixer (Q1404Q1407) to be mixed with the 1st RX LO signal, resulting in the 64.455 MHz 1st RX IF signal. The 1st RX IF

40、signal is amplified by the 1st RX IF AMP (Q1810) and passed through the 1st RX IF filter (FI1401). The filtered 1st RX IF signal is amplified by another 1st RX IF AMP (Q1414), and then applied to the 2nd RX IF circuits. 2ND RX IF CIRCUIT (MAIN UNIT) The 1st RX IF signal from the 1st RX IF circuits i

41、s applied to the 2nd RX IF mixer (D1812, D1813) to be mixed with the 2nd RX LO signal, resulting in the 455 kHz 2nd RX IF signal. The 2nd RX IF signal is passed through the trans- former-coupled filter (L1446) and 2nd RX IF filter (FI1402), and amplified by the 2nd RX IF AMPs (Q1415, Q1412 and Q1413

42、), and then applied to the 3rd RX IF circuits, through the buffer (Q1411). 3RD RX IF CIRCUIT (MAIN UNIT) The 2nd RX IF signal from the 2nd RX IF circuits is applied to the 3rd RX IF mixer (IC1402) to be mixed with the 3rd RX LO signal, resulting in the 36 kHz 3rd RX IF signal. The 3rd RX IF signal i

43、s passed through the 3rd IF SW (IC1403) and LPF (L1454.

46、 UNIT) The 3rd RX IF signal from the 3rd RX IF circuits is passed through the buffer (IC3602, IC3603), and then applied to the A/D converter to be converted into digital audio signal. The converted digital audio signal is applied to the DSP (IC8201) on the DSP-2 UNIT, and demodulated and proc- essed

47、. The demodulated signal is applied to the CODEC (IC3611) to be converted into analog AF signal. The AF signal is passed through the buffer (IC3615), LPF (IC3003) and AF mute SW (IC3005), and then applied to the electronic vol- ume (IC3008), which adjusts the AF output signal in level. The level-adjusted AF signal
