Amplifier Research 100W1000 RF Amplifier, 1 – 1000 MHz, 100W

The Amplifier Research 100W1000 is a solid-state, air-cooled RF power amplifier delivering 100 watts across 1 to 1000 MHz. Push-pull circuitry in high-power stages minimizes distortion and enhances stability across demanding test and evaluation environments. The Digital Control Panel provides local and remote operation via LCD touch screen and rotary knob, with comprehensive power monitoring and protection circuits.

Forward and reflected power are displayed in real time. This amplifier excels as a primary source or driver stage in EMC compliance testing, communication system characterization, antenna measurements, and component validation.
