An active 600 GHz frequency multiplier-by-six S-MMIC

For submillimeter-wave generation we present an active six-fold frequency multiplier circuit operating with an average output power of -16 dBm without post amplification and a measured output frequency range from 580 to 625 GHz. The S-MMIC is realized in a metamorphic HEMT technology with 35 nm gate-length for convenient multifunctional circuit integration.
