Abstract

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 results shows the performance of the underlying large-signal mHEMT models. The MMIC is realized in metamorphic HEMT technology with 100 nm gate-length.
