Analysis and Measurement of a Millimeter-Wave Holographic Power Combiner for 5 IMPATT Oscillators.

摘要

IMPATT diodes are the most powerful solid-state devices for millimeter-wave frequencies, but their power still has to be increased to compete with vacuum tubes. This can be accomplished by combining the power of an oscillator ensemble. In the millimeter-wave region, the most efficient method to perform power combining is holography. A 65 GHz holographic power combiner for five IMPATT oscillators has been designed and experimentally investigated utilizing quasi-optical multiple-device circuit technology.
