The Amplifier Research 200L is a self-contained, air-cooled, solid-state RF amplifier engineered for laboratory and test environments requiring broadband coverage from 1 MHz to 200 MHz. It delivers 200 W of continuous-wave power and 400 W pulsed output with over 500 W peak pulse capability. The amplifier accepts 1 mW input for rated output, provides 53 dB gain, and maintains ±1.5 dB flatness across its instantaneous bandwidth. It reproduces AM, FM, and pulse modulation faithfully and operates into any load impedance without shutdown or damage—a critical advantage in field testing and measurement scenarios.
