Narrow band quasi-circulator module design used in a transmit / receive module

摘要

This paper presents the design and the measured performances of a narrow band MMIC quasi-circulator module. Its design implements active divider and combiner. The device demonstrates a noise figure of 5.5 dB and an output power of 18 dBm with associated gains of 4 dB and 7.6 dB for the receive and transmit path, respectively.
