Amplifier Research 600A225A Amplifier – High Power & Advanced Features
The Amplifier Research 600A225A is a state-of-the-art, self-contained, air-cooled broadband amplifier specially designed for applications that require immediate bandwidth and high gain performance. Utilizing advanced push-pull LDMOS circuitry across all high power stages, the 600A225A operates with low distortion and enhanced stability, making it an optimal choice for demanding RF applications.
When coupled with an RF sweep generator, this amplifier delivers a minimum of 600 watts of swept power, ensuring high performance in various testing environments. The integrated Digital Control Panel (DCP) furthers its versatility, providing both local and remote control options. Featuring a 3.75-inch diagonal graphic display, the DCP allows users to easily navigate through settings using menu-assigned softkeys, a single rotary knob, and four dedicated switches for comprehensive control and status reporting.
The operational display showcases crucial metrics, including Forward Power, Reflected Power, and overall control status, facilitating precise monitoring of amplifier performance. Notable features include a gain control for optimal adjustments, a forward RF sample port for accurate power readings, and a reflective RF sample port, making it an indispensable tool in RF measurements.
Comprehensive connectivity options are a hallmark of the 600A225A, with all essential amplifier control functions and status indications available remotely via GPIB/IEEE-488, RS-232, and USB formats. The back panel hosts bus interface connectors, while a keylock on the front panel assures reliable control over local or remote operations. Designed with efficiency in mind, the amplifier employs a high-efficiency universal input and power factor corrected switching power supply, delivering consistent DC to all internal components.
