Abstract
We demonstrate a broadband active frequencymultiplier- by-six for the W-band (75-110GHz), mounted in a waveguide package. The frequency-multiplying function is performed in a single MMIC using a cascade of balanced tripler and doubler stages. The MMIC, realized in metamorphic HEMT technology, is mounted by wire bonding and high performance waveguide-to-microstrip transitions into a split-block waveguide module containing an integrated voltage supply board. The module achieves an output power of 2.5dBm, with an associated conversion gain of 0.5 dB, and a 3-dB output bandwidth of 21.5%, corresponding to a frequency range from 83 to 103 GHz. Unwanted harmonics in the output spectrum are suppressed by more than 18dB. The application of the employed packaging technique to frequencies up to 325GHz is discussed.
