Design of Low Power Medical Device

Wei Cai and Frank Shi, University of California, USA

Abstract

This paper describes the design of an MMIC phase shifter which can be used in a 4-channel 26-28 GHZ transmitter IC. The MMIC phase shifter is used for 5G RF front Ended applications. MMICs usually include power amplifiers with 4-bit digital phase shifters to make the phase adjustable. The whole design was used for the transmit chain of a mobile device and in a base-station. Future topology will continue to be improved.
