Icom IC-PW2 High-Power Amplifier

Further details of Icom IC-PW2 High-Power Amplifier

The IC-PW2 uses new 65 V LDMOS power transistors, MRFX1K80HR5 and a high-efficiency power supply. 1 kW output and 1-hour continuous transmission can be achieved with 200 V AC input (at ambient temperature 25 degrees Celsius). It can be operated at full power operation after booting up the IC-PW2. Of course, you can operate it continuously, even in long contest hours, or FT8 operation.

The IC-PW2 has succeeded in realizing the world’s first DPD as a linear amplifier for amateur radio in combination 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.

Two radio inputs and six antenna connectors provide fully automatic antenna switching capabilities. Each antenna can be selected independently when making a band change 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 dual bands at once by using two antennas.

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

Conventional linear amplifiers require two multi-band BPFs 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.

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.

With compatible Icom radios, various settings are easy, and you can get the full performance out of the IC-PW2. When you operate the transceiver by changing bands and frequency tuning, the IC-PW2 automatically works in conjunction with it. It provides an extremely quick response in contests and multi-band operations.

By using mechanical relays, the antenna tuner can quickly 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.
