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 speciﬁed voltage. This

will ruin 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 transceiver’s

front-end.

To upgrade quality, any electrical or mechanical parts

and internal circuits are subject to change without notice

or obligation.

convenience.

ORDERING PARTS

1. Make sure that the problem is internal before dis-assem-

bling the transceiver.

2. DO NOT open 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 long 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 dB to 50 dB attenuator between the

transceiver and a Deviation Meter or Spectrum Analyzer,

when using such test equipment.

8. READ the instructions of the test equipment thoroughly

before connecting it to the transceiver.

CIRCUIT DESCRIPTION

3-1 RECEIVER CIRCUITS

RF CIRCUIT (PA UNIT)

• While operating on the HF, 50 MHz and 70 MHz bands

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 ﬁltered RX signal is passed through the TX/RX SW

(RL801) 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 the BPFs, depend-

ing on the operating frequency, to remove unwanted signals.

(See the BPF TABLE on page 3-2.)

The ﬁltered signal is applied to the pre-AMP circuit.

PRE-AMP CIRCUIT (MAIN UNIT)

When the pre-AMP is turned ON, the RX signal is ampliﬁed

by the pre-AMP (Q3201).

The ampliﬁed signal is applied to the 1st RX IF circuits.
