The 12500A225 from AR RF/Microwave Instrumentation is a Solid-State Amplifier that operates from 10 kHz to 225 MHz. It delivers a CW output power of more than 12.5 kW with 71 dB of gain and has a rise/fall time of less than 10 ns. This amplifier utilizes push-pull MOSFET circuitry in all high-power stages to lower distortion and improve stability. It can reproduce AM, FM or Pulse modulation appearing on input signals with harmonic distortion of -20 dBc (at 8000 W). This amplifier is ideal for RF susceptibility testing, antenna and component testing, watt meter calibration, particle accelerators, plasma generation & communications applications and can be used as a driver for higher-power amplifiers.
The 12500A225 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. It uses a color LCD touch screen and a single rotary knob to offer status reporting and control capability. The display provides an operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status. It also includes special features such as gain control, internal automatic level control (ALC) with front panel control of the ALC threshold, and RF output level protection. All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format or RS-232 hard wire.
The amplifier is available in an enclosure that measures 170.2 x 88.9 x 182.8 cm with N-Type (female) input and EIA 3-1/8 (male) output connectors. It requires an AC supply from 187 to 264 V (Delta 4-wire) or from 380 to 460 V (Wye 5-wire) and consumes less than 55 kW of power. The export classification for this equipment is EAR99.
