Dual-Band Dual-Output Doherty Power Amplifier for Unsynchronized Time-Division Duplexing
IEEE transactions on microwave theory and techniques, 2023Conventional multiband power amplifiers (PAs), when working in time-division duplex (TDD), require the transmit–receive intervals of all bands to be synchronized. This is an undesirable constraint in modern radio base stations.

GaN MMIC broadband Doherty power amplifier
2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013A quarter-wavelength transformer, phase compensation network, offset line are the bandwidth limiting factors of Doherty PAs. In this paper, we expand the bandwidth of the Doherty PA by employing a new structure. The conventional phase compensation network is merged into an input matching circuit and the offset line is resonated-out by an inductor.
