A novel configuration of balanced frequency InGaAs pseudomorphic high electron mobility transistor (PHEMT) monolithic microwave integrated circuit (MMIC) tripler is proposed. A resonant LC filter is used to eliminate the fundamental frequency and a phase delay line is employed to suppress the second harmonic. The separation of the independent phase shifters makes the tripler more compact and flexible. The conversion loss of the tripler operating from 12 to 36 GHz is less than 9.4 dB at 9-dBm input power. As compared to the third-harmonic frequency, the fundamental frequency is suppressed more than 21. 4 dB while for the second harmonic is more than 22.3 dB at 36 GHz.
