Abstract : An apparatus for frequency stabilizing a microstrip oscillator using an integrated diplexer as a frequency discriminator. The crossover frequency of the microstrip diplexer is used in a feedback arrangement to stabilize a millimeter-wave oscillator. The diplexer is coupled to the output of the oscillator and detects a shift from the desired oscillator output frequency. This shift in frequency is converted to a voltage for controlling the varactor tuning element of the oscillator to thereby return the oscillator to the desired operating frequency. Means are also provided for sensing a temperature change in the diplexer and for insuring that the oscillator output frequency is maintained at the desired frequency regardless of this temperature change.
