Abstract

This paper presents an novel configuration of balanced frequency InGaAs pseudomorphic high electron mobility transistor (PHEMT) monolithic microwave integrated circuit (MMIC) tripler with Ka-band output frequency (39 GHz). A resonant LC filter is used to eliminate the fundamental frequency and a phase delay line is employed to suppress the second harmonic. By using a class B transistor bias point and carefully selecting its input and output terminations, a conversion loss of 16.36 dB for an 10 dBm input signal have been obtained. As compared to the third-harmonic frequency, the second harmonic is more than 28.1 dB at 39 GHz. It is very useful for applications in the wireless communication and radar systems.
