160 school house road, souderton, pa 18964-9990 usa phone 215-723-8181?fax 215-723-5688 model 150a400 m1, m2, m3 150 watts cw 100 khz - 400 mhz the model 150a400 amplifier is a self-contained, broadband unit designed for laboratory applications where instantaneous bandwidth, high gain and moderate power output are required. utilization of push-pull mosfet circuitry lowers distortion, improves stability and allows operation into any load impedance without damage. the model 150a400, when used with an rf sweep generator, will provide a minimum of 150 watts of swept power. there is a digital display on the front panel to indicate the operate status and fault conditions when an over temperature, power supply, or amplifier fault has occurred. the unit can be returned to operate when the condition has been cleared. the 150a400 includes digital control for both local and remote control of the amplifier. this 8-bit risc microprocessor controlled board provides both ieee-488 (gpib) and asynchronous, full duplex rs-232 control of all amplifier functions. all amplifier control functions and status indications are available remotely in gpib / ieee-488 format. the buss interface connector is 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. housed in a stylish, contemporary enclosure, the model 150a400 provides readily available rf power for typical applications such as rf susceptibility testing, antenna and component testing, watt meter calibration, and use as a driver for higher power amplifiers. 0 50 100 150 200 watts 1 10 100 1000 frequency (mhz) 150a400 typical power output 0.001 0.01 0.1 linear @ 3db compression linear @ 1db compression rev050401
