Abstract :
For broadband signal generation in the high millimeter-wave range we present a frequency multiplier-by-eight MMIC. The measured output tuning bandwidth from 220 to 320 GHz almost covers the entire WR-03 waveguide band (220-325 GHz). On chip interstage and post amplification result in a maximum output power of 2.5 dBm at an output frequency of 260 GHz. Due to the high multiplication factor in-band harmonics are measured with a frequency-selective method and verify the dominant presence of the wanted eighth harmonic. The MMIC is realized in a metamorphic high electron mobility transistor (mHEMT) technology with a gate length of 35nm.
