Abstract :
Three completely integrated S-band parametric amplifier modules, of a type ultimately suitable for spaceflight applications, have been constructed and tested. Each consists of a single-stage thin-film-microstrip 2.25-GHz parametric amplifier, closely integrated with a waveguide-mounted isolator-coupled 14-GHz Gunn-effect pump oscillator in a 6-in/sup 3/ aluminum housing weighing less than 0.6 lb. The pertinent measured characteristics of the three modules include: 2.25-GHz center frequency, 15-dB maximum gain, 76-90-MHz 1-dB bandwidth, and 139-170/spl deg/ K passband temperature.
