Logimetrics A600L

The Logimetrics A600L is a broadband microwave amplifier delivering 200 W CW minimum output across the 1.0–2.0 GHz band. Built around a Traveling Wave Tube (TWT) with regulated helix, filament, and grid power supplies, it provides 30 dB saturated gain and sustained performance in demanding RF test and system environments.
