Abstract :
This paper presents a 60GHz transmitter (TX) based on the outphasing technique. It avoids amplifying variable-envelope signals and reconstructs the modulated signals by vector summing two constant-amplitude phase-modulated signals using an on-chip power combiner. The proposed design proves to have higher linear output power with better average efficiency compared to existing 60GHz solutions.
