Abstract : A transistor oscillator driver circuit has been constructed that produces 1.25 watts from 1.06 to 1.13 Gc. Another prototype oscillator has been tested and produces 1.0 watt from 1.4 to 1.5 Gc. Test jigs for the corresponding frequency multipliers have been constructed. A couple of silicon varactor diodes have given 40% conversion efficiency in the quadrupler jig going from 1.1 Gc to 4.4 Gc. Also, 60% efficiency was achieved with a gallium arsenide diode in a doubler jig going from 4.4 Gc to 8.8 Gc. The sextupler jig is complete and several diodes are being evaluated. (Author)
