The Model 400S1G4 is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Quadrature coupled circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 400S1G4, when used with a sweep generator, will provide a minimum of 375 watts of RF power. -
