Development of an extremely wide-band planar frequency doubler from Q-band to W-band

  • Cam Nguyen


A very broadband Q- to W-band MIC frequency doubler with a 28-GHZ band-width, employing a unique planar balanced circuit configuration, has been developed with good performance. Using two beamlead Schottky barrier diodes as varistors, the doubler exhibits an output power of 7±1 dbm and conversion loss of 13±1 db over the 66 to 94 GHZ output frequency range. The development demonstrates a unique concept in realizing wideband planar millimeter wave solid-state sources.
