Amplifier Research 100A400AM20 Low Power RF Amplifier

The Amplifier Research 100A400AM20 Low Power RF Amplifier is a solid-state broadband amplifier that provides consistent RF power for instantaneous bandwidth. The Amplifier Research 100A400AM20 RF Amplifier produces reliable RF power as low as 4kHz and reaches 400MHz to test for a vast range of applications. The immense power range allows this RF amplifier to test for the MIL STD 461 CS114 standard and its bulk current testing capabilities can confirm all the CS114 test curves.

This solid-state amplifier also remains safe even in high-usage situations thanks to an RF input leveling circuit that prevents RF input overdrive and DC voltage that's easily removed to prevent issues with overtemperature. The Amplifier Research 100A400AM20 Low Power RF Amplifier allows for easy use through front panel gain control to quickly adjust the output level. The portable amplifier offers highly efficient production in any environment while boasting an excellent power output that stretches from 10 watts to 85 watts.
