Amplifier Research 2500A225 The Amplifier Research 2500A225 RF Amplifier is a self-contained, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. The amplifier is air cooled using internal self-contained liquid cooling for high performance and reliability. Push-pull LDMOS circuitry is utilized in all high power stages in the interest of low distortion and improved stability.The Amplifier Research 2500A225 is equipped with a Digital Control Panel (DCP), providing local and remote control of the amplifier. The DCP uses a 3 ¾ inch diagonal graphic display, menu assigned softkeys, a single rotary knob, and four dedicated switches to offer extensive control and status reporting. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status.All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hard wire and fiber optic, and USB and Ethernet. The buss interface connectors are located on the back panel and positive control of local or remote operation is assured by a keylock on the front panel of the amplifier.High efficiency universal input, power factor corrected switching power supplies provide DC to all internal sub-assemblies.The AR 2500A225 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.Specifications for the Amplifier Research 2500A225 include:RATED OUTPUT POWER ……………………………………….. 2500W, 10 kHz–50 MHz2500–1900W, 50 MHz–225 MHz (derating slope of 3.43W/MHz)INPUT FOR RATED OUTPUT ………………………………….. 1.0 mW MaxPOWER OUTPUT FOR 1dB COMPRESSION ………………. 1800W, 10 kHz-50 MHz1800–1200W. 50 MHz-225 MHz (derating slope of 3.43W/MHz)FREQUENCY RESPONSE ……………………………………….. 10 Khz-225 MHz instantaneouslyGAIN (at max. setting) …………………………………………… 64 dB min.FLATNESS …………………………………………………………… ± 3.5 dB max± 0.8 dB with int. levelingGAIN ADJUSTMENT (continuous range) ……………………. 16 dB minimumINPUT IMPEDANCE ………………………………………………. 50 ohms, VSWR 2.0:1 maxOUTPUT IMPEDANCE …………………………………………… 50 ohms nominalMISMATCH TOLERANCE ……………………………………….. 100% rated power without foldback up to 6.0:1 mismatch, above which maylimit to 1250w reflected powerMODULATION CAPABILITY …………………………………….
