X-Band Solid State Module.

Abstract

This report describes an eighteen-month program to develop an X-band solid state amplifier. The amplifier is the critical component of an all solid state tranceiver module for use in active element, airborne, phased array radars. The performance goals were an output power of 4 W (min.) with 25 dB gain over the 9 to 10 GHz frequency band with an efficiency > or=20% under pulsed conditions. Two approaches were pursued to meet these goals: an all GaAs FET amplifier and an FET/Read diode hybrid amplifier. At the completion of the program, two amplifiers of each type were delivered. An all FET amplifier module with a three-stage driver and a balanced output stage delivered an output power of 4W with 24 dB gain over the 8.9 to 9.9 GHz frequency band (l dB) with 20% efficiency including bias circuit losses. An FET/Read diode hybrid amplifier delivered 5W over with 25 dB gain at 9.5 GHz over a 600 MHz bandwidth with l9% efficiency. Extensive cw and pulsed measurements indicate that the all FET amplifier is best suited for phased array radar applications. (Author)
