An active frequency-tripler MMIC achieving an output frequency of 315 GHz is presented. Without the use of postamplification the frequency-tripler generates an average output power of -10.1 dBm in the output frequency range from 285 to 315 GHz. At 303 GHz the measured output power is -9.3 dBm with an input power of 10 dBm. The comparison to the simulated results shows the quality of the underlying large-signal mHEMT models. The MMIC is realized in a metamorphic HEMT technology with 50 nm gate-length and uses only 0.5 x 0.75 mm(2) of chip space for convenient integration into multifunctional MMIC circuits. An integrated version with output buffer amplifier is presented generating -0.5 dBm of output power at 288 GHz.
