ICOM IC-PW2 HF/50 MHz ALL Band 1 kW Linear Amplifier

Key Features

• Powerful SO2R capabilities
• Optional PC remote-control software will provide a remote-control operation through a LAN. Remote power ON/OFF from the PC and various operation of the radio will be possible.
• The antenna tuner uses mechanical relays to retune the operating band in two to three seconds. The IC-PW2 has also succeeded in reducing unnecessary emissions during tuning. The antenna tuner works even when the power amplifier function is not used.
• A remote-control cable (3 m, 9.8 ft) enables the amplifier to be mounted away from the radios for a big station installation. The 4.3 inch color display is a touch screen with a graphical user interface. Connected antennas are graphically shown on the display.
• 1kW Output at Fully Duty Cycle

High Power & Full Duty Cycle Operation

The IC-PW2 uses new 65 V LDMOS power transistors (MRFX1K80HR5) and a high-efficiency power supply. Achieve a 1kW output with a 200V AC Input. The IC-PW2 instantly operates at full power once turned on. Use the PW2 for long contest hours or full-duty FT8 operation.

Increased Linearity & Clean Transmission with the Digital Pre-Distortion (DPD) Technology (with the IC-7610)

This technology corrects the signal distortion from the IC-PW2, by applying inverse distortion to the output signal from the IC-7610 exciter in advance*2.

*1 According to Icom’s research as of July 2023.
*2 Not applied in non-linear modulation such as FM, FSK, and MSK modes.

2 × 6 Automatic Antenna Selector

Two radio inputs and six antenna connectors provide fully automatic antenna-switching capabilities. Each antenna can be independently selected when changing a band on either transceiver. You can operate it as if you had two linear amplifiers. When using dual independent receivers, which the IC-7610 and IC-7851 have, you can watch two bands at once by using two antennas.

Powerful SO2R Features

Single Operator Two Radios (SO2R) operation is possible with one IC-PW2. While you are making a call on one radio*1, you can watch another band on the other radio. The transmitter lockout function*2 prevents simultaneous transmission of two radios during SO2R operation.

*1 Performance may deteriorate depending on the performance/specifications of the BPF and exciter, antenna installation conditions, and other factors. In such cases, please take measures such as using two sets of BPFs.

*2 Compatible Radio linked operation is available with IC-7851, IC-7610, and IC-7300 (firmware upgrade required.)

SO2R Operation Possible with Just One Multi-band BPF

Conventional linear amplifiers require two multi-band bandpass filters (BPF) to prevent suppression of receive sensitivity by their own transmit signal when operating SO2R. However, the IC-PW2 automatically connects the multi-band BPF to the receiving radio when you select either radio to transmit. This makes SO2R operation possible with just one Multi-band BPF.

RX-ANT Connectors for Multi-band BPF and External Equipment

User supplied bandpass filters (BPF), preamps, and attenuators can be connected to the [RX-ANT] connectors. When you use two radios with the IC-PW2, one multi-band BPF can be shared with these radios by switching the receiving radio. In addition, the band switching of multi-band BPF can be controlled from the band signal output connector. The [BAND 1], [BAND 2] signal output connectors, can each be set to either [INPUT 1], [INPUT 2], transmitter side, or receiver side. It can be linked with band switching of various external devices.

Use compatible Icom radios to get the full performance out of the IC-PW2. Accessing various settings is easy. When you operate the transceiver by changing bands and frequency tuning, the IC-PW2 automatically works in conjunction. It provides a rapid response in contests and multi-band operations.
