This interim report covers the second six months of an eighteen-month program to develop an X-band solid state amplifier. The amplifier is the critical component of an all solid state transceiver module for use in active element, airborne, phased array radars. The performance goals are an output power of 5 W with 25 dB gain over the 9 to 10 GHz frequency band with an efficiency greater than or equal to 20 under pulsed conditions. Two approaches are being pursued to meet these goals an all GaAs FET amplifier and an FETRead diode hybrid amplifier. At the completion of the program, two amplifiers of each type will be delivered. The effort during this period included continuation of GaAs FET development with emphasis on obtaining devices suitable for the power amplifier stage. The three-stage driver amplifier development was completed. An output power of 1.6 W with 20 dB gain and 26 efficiency over the 9 to 10 GHz frequency band was achieved, meeting the design goals. Extensive pulse measurements have been made on several FET amplifiers, and the results indicate that there are are no significant limitations to the use of these amplifiers in active-element, phase array radar systems.
