HF/50 MHz 1 kW LINEAR AMPLIFIER
IC-PW2
1 kW Output at Full Duty Cycle
Single Operator Two Radios (SO2R) with One IC-PW2
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 and 1-hour continuous transmission can be achieved with 200 V AC input (at ambient temperature 25 ℃.) 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.
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.

CloseIngress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
| IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
|---|---|
| IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
| IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
|---|---|
| IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
| IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
| IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
| IPx4 | Protected against water splashed against the equipment from any direction |
