20W Class-AB Amplifier w/ Heatsink , from 20 to 2000 MHz


Product Overview
The ZHL-20W-202-S+ is a Class AB, high-power amplifier providing 20W saturated power over the 20 to 2000
MHz band, ideal for a variety of high-power test setups as well as applications including communications,
radar and more. The ruggedly-designed amplifier provides unconditional stability and built-in self-protection
against reverse polarity, excessive drive and overheating. The amplifier’s output stage is further protected
