Amplifier Research 150A250 RF Amplifier, 100 kHz - 250 MHz, 150W

Amplifier Research 150A250 Amplifier

Engineered for precision and efficiency, the Amplifier Research 150A250 Amplifier is a self-contained, broadband unit, ideal for laboratory environments that demand instantaneous bandwidth, high gain, and moderate power output. Utilizing advanced push-pull MOSFET circuitry, this amplifier minimizes distortion while enhancing stability, allowing it to operate safely into any load impedance.

With a minimum output of 150 watts when paired with an RF sweep generator, the 150A250 is a powerhouse for a variety of applications, including RF susceptibility testing, antenna and component testing, wattmeter calibration, and serving as a driver for higher power amplifiers.

The front panel features an integrated digital display, providing real-time indicators of operational status along with fault conditions such as over-temperature and power supply issues. The amplifier's performance can quickly resume once the fault has been resolved, ensuring uninterrupted operations.

This model incorporates state-of-the-art digital control, offering local and remote operation capabilities through an 8-bit RISC microprocessor-controlled circuit. Communication is seamless with both IEEE-488 (GPIB) and full duplex RS-232 interfaces available for comprehensive control over all amplifier functions.
