High Power and Full Duty Cycle Operation

LDMOS Transistor ＜MRFX1K80HR5＞

The IC-PW2 uses new 65 V LDMOS power transistors, MRFX1K80HR5 and a high-efficiency power supply. 1 kW output at full duty cycle can be achieved with 200 V AC input. 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 full-duty FT8 operation.

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

The IC-PW2 has succeeded in realizing the world's first^*1 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^*2.

*1 According to our 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 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.

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 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*.

* 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.

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.

Completely Linked with Icom Radio Operation*

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.

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

Built-in Automatic Antenna Tuner

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.

Detachable Controller with Touch Screen Color Display

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.
