Abstract

- A technique to design a broadband two-stage frequency tripler is proposed. The 1 st and the 2 nd harmonics obtained from the first stage are mixed in the second stage, getting the 3 rd harmonic. Between the two stages, there is a two-pole filter which lets the amplitude of the 1 st harmonic increase and the amplitude of the 2 nd harmonic decrease when the frequency increases. Consequently, a large 1 st harmonic is always mixed with a small 2 nd harmonic, and vice versa, which equalizes the amplitude of the mixing product, i.e., the 3 rd harmonic, over a large bandwidth. Together with a frequency doubler and a buffer amplifier, this frequency tripler is used in a frequency sixtupler. A proof-of-concept circuit is designed and implemented in 250 nm indium phosphide (InP) double-heterojunction bipolar transistor (DHBT) technology. For an input power of 6.3 dBm, the sixtupler has an output power between 0 dBm to 4.6 dBm in the output frequency range from 135 GHz to 183 GHz. It exhibits up to 13 dBc rejection ratio of the undesired 4 th , 5 th , and 7th harmonics. The sixtupler consumes a dc power of 100 mW, and achieves a peak power efficiency of 2.5%.
