This paper presents a Ka- to F-band ultra-broadband subharmonic mixer (SHM) using the standard 90-nm CMOS process. The proposed SHM employs a distributed amplifier and antiparallel diode pair configuration to realize wide operation bandwidth from 33 to 103 GHz, low conversion loss from 0.52 to 3.35 dB, good local oscillation (LO)-to-RF isolation greater(More)
This paper presents the implementation of a broadband quasi-circulator through a cascading distributed balun using a 90-nm CMOS process. The isolation, |S31|, of the proposed three-port quasi-circulator can be acquired through the phase cancelation technique, by connecting an additional distributed amplifier in parallel between ports 1 and 3.
