Abstract : Progress is reported on a program to produce a miniature solid-state tunable source in the 16 Gc/s to 16.5 Gc/s frequency band. A one-half-watt fundamental frequency transistor oscillator that is mechanically tunable from 970 Mc/s to 1040 Mc/s has been completed. In addition, an electronically-tunable frequency oscillator that provides 200 mW to 400 mW tunable from 990 Mc/s to 400 mW tunable from 990 Mc/s to 1035 Mc/s has been developed. Transistor oscillator doublers that generate 2.45 watts at 1000 Mc/s and transistor oscillator triplers that generate up to 2.90 watts in the 1250 Mc/s range have been tested. A Bimode varactor tripler has demonstrated an over-all efficiency of 33 percent at an output frequency of 9.9 Gc/s; an output of 230 mW is generated at X-band. A similar Bimode quadrupler was constructed with an efficiency close to 30 percent and an X-band output of 190 mW. The potential of step-recovery diodes as high-order multipliers is also being investigated. A times-10 multiplier has generated 35 mW at X-band.
