225A

225A is a radiofrequency (RF) power amplifier module produced by the United States-based electronics company Amplifier Research. It is characterized by its compact size and high-frequency operation.

The 225A is designed to operate at frequencies up to 20 GHz, making it suitable for a variety of applications, including radar, telecommunications, and scientific research. The module provides 25 watts (W) of continuous wave (CW) output power, and it can handle a maximum input power of 500 W.

The 225A is built with metal components to provide mechanical shock and environmental protection. An internal voltage-adjust bias network for three-stage of amplifiers provides option to regulate or to have higher return loss.

Its input and output features SMA connectors and the operating temperature range is -54°F (-48°C) to 116°F (47°C). The amplifier is capable of operating in the frequency spectrum from DC to 20 GHz.

The unit weighs 11 pounds (5 kg) and dimensions 15.25 inches (38.8 cm) long by 7.5 inches (19.1 cm) wide by 11.93 inches (30.3 cm) height. This particular RF power solution is suitable for applications that require compact form factor and high-performance operation.
