Abstract
This article presents a fully integrated
millimeter-wave (mmW) transceiver front end covering
24.25–29.5 GHz. It features a wideband Doherty power
amplifier utilizing adaptive bias and a transmit/receive switch
(TRX-switch) that has embedded low noise amplifier to antenna
matching. The phase shift of 90 ◦ to the Doherty auxiliary
amplifier is achieved using a separate IQ-mixer with rearranged
phases in the auxiliary path, ensuring a wideband 90 ◦ phase
shift, and avoiding 3-dB loss from radio fr
