Abstract : Several gallium-arsenide diodes having peak currents of 50 ma and cutoff frequencies of l5-l7 Gc were tested in a low-inductance strip-line circuit. At frequencies between 6l00 and 6700 mc/sec, rf output powers of 0.9 milliwatts were measured. Diodes are presently being fabricated with objective cutoff frequencies of 20 Gc and higher in order to raise the power level. A waveguide tunable oscillator circuit was designed and constructed. Tests of this circuit are awaiting the next lot of higher cutoff frequency diodes. (Author)
