AR shrinks the size of its RF power amplifiers

The A series amplifiers provide readily available RF power for applications.

New design techniques at AR RF/Microwave Instrumentation have enabled the company to produce smaller, more compact solid-state amplifiers with just as much power as the older, larger models. The new A series amplifiers are not only 25% to 50% smaller than previous models without a reduction in power, but also more efficient, using less energy than other amplifiers.

The A series comprises three models:

• the Model 2500A225, which covers a frequency range of 10 kHz to 225 MHz and provides rated output power of 2500 W;

• the Model 1000A225, with a frequency range of 10 kHz to 225 MHz and rated output power of 1000 W; and

• the Model 500A250A, with a frequency range of 10 kHz to 250 MHz and rated output power of 500 W.

Each model is equipped with a digital control panel that allows local and remote control of the amplifier. The control panel features a 3-3/4-in. diagonal graphic display, menu-assigned softkeys, a single rotary knob, and four dedicated switches for control and status reporting. Units can be controlled remotely through IEEE 488, RS-232, USB, and Ethernet interfaces.

The A series amplifiers provide readily available RF power for applications, such as RF susceptibility testing, antenna and component testing, wattmeter calibration, particle accelerators, plasma generation, and communications. They can also be used a driver for higher-power amplifiers.
