Abstract

A compact balanced frequency MMIC doubler using compensated capacitive line in Marchand balun is proposed. With multi-coupled lines technology, the balun is applied to a balanced doubler successfully. Compared with the conventional Marchand balun, more than 55% reduction in the length of coupled line can be achieved. Implemented by a PHEMT process, the compact monolithic balanced frequency doubler with better performance can be obtained. An operation bandwidth from 20 to 44 GHz with the best conversion loss of 8.4 dB at 25GHz can be achieved. In addition, the fundamental frequency suppression is better than 28.9 dB, and the chip dimension is as small as 0.41 × 0.68 mm2.
