Overview
The Amplifier Research 200A400A is a self-contained, aircooled, broadband, completely solid state amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull LDMOS circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 200A400A, when used with an RF sweep generator, will provide a minimum of 200 watts of swept power.
The Model 200A400A is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a color LCD touch screen and a single rotary knob to offer status reporting and control capability. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status. Special features include a gain control, pulse input capability, forward RF sample port and a reflective RF sample port for precise power measurements.
All amplifier control functions and status indications are available remotely in GPIB/IEEE488, RS-232, RS-232 fiber optic, Ethernet, and USB format. The buss interface connectors are located on the back panel and positive control of local or remote operation is assured by a switch on the front panel of the amplifier.
High efficiency universal input, power factor corrected switching power supplies provides DC to all internal sub-assemblies.
Housed in a stylish, contemporary enclosure, the Model 200A400A provides readily available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, particle accelerators, plasma generation, communications and use as a driver for higher power amplifiers.
