Abstract :
The design of Q band IMPATT diode cavity combiners is discussed. The design is based on a three-step closed form algorithm. The first step is the characterization of the passive circuit (cavity and diode package) using an automatic network analyzer. In the second step, a computer program is used to generate diode device lines. The third step is the load line synthesis for predictable operation as either an injection-locked oscillator or a stable negative resistance amplifier. These procedures were used to design a three-diode, two-stage amplifier using 2-watt, 44-GHz GaAs IMPATT diodes. An output power of 3 watts with 11 dB gain was achieved.
