Abstract

This letter introduces a new wideband output combiner for outphasing power amplifier. The conventional two non-commensurate transmission lines are replaced with two reconfigurable T-type networks loaded with shunt varactors. In virtual of the proposed architecture, the bandwidth limitation that happens in the conventional combiner is greatly reduced. To provide reactance compensation in a large op...
