An active frequency multiplier-by-nine MMIC with integrated buffer amplifier reaching 94 GHz from X-band is presented. The multiplier-by-nine generates an average output power of -7.7 dBm in the frequency range from 82 to 102 GHz. At 94 GHz the measured output power is -6.4 dBm with an input power of 10 dBm. The suppression of unwanted harmonics is better than 23 dBc. The comparison to the simulated...
An active frequency multiplier-by-nine MMIC with integrated buffer amplifier reaching 94 GHz from X-band is presented. The multiplier-by-nine generates an average output power of -6.5 dBm in the frequency range from 87 to 99 GHz. At 94 GHz the measured output power is -5 dBm with an input power of 9 dBm. The suppression of unwanted harmonics is better than 15 dBc. Phase-noise measurements prove the...
We demonstrate a broadband active frequency-multiplier-by-six for the W-band (75-110 GHz), 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...
