Abstract:

Progress is reported on a program to produce a miniature solid-state tunable source in the 16 Gcs to 16.5 Gcs frequency band. A one-half-watt fundamental frequency transistor oscillator that is mechanically tunable from 970 Mcs to 1040 Mcs has been completed. In addition, an electronically-tunable frequency oscillator that provides 200 mW to 400 mW tunable from 990 Mcs to 400 mW tunable from 990 Mcs to 1035 Mcs has been developed. Transistor oscillator doublers that generate 2.45 watts at 1000 Mcs and transistor oscillator triplers that generate up to 2.90 watts in the 1250 Mcs range have been tested. A Bimode varactor tripler has demonstrated an over-all efficiency of 33 percent at an output frequency of 9.9 Gcs 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.
