High performance 0.15 µm gate pHEMT V-band tripler using compact microstrip resonant cell (CMRC) technique

A V -band current reuse frequency tripler is developed in 0.15um pseudomorphic high electron mobility transistor (pHEMT) technology. This tripler combines the compact microstrip resonant cell (CMRC) topology for suppress unwanted harmonic and current-reuse technique to improve the conversion gain. At 60 GHz, the tripler achieved as minimum conversion gain of -16.6 dB at an input power of 8 dBm; the suppressions of the fundamental and second harmonic frequencies were 22 dB and 27 dB, respectively.
