Efficient waveguide power combiners at mm-wave frequencies

Activity: Talk or presentationTalk or presentation at a conference


In this work, an efficient power combiner for mm-wave frequency transmitters is investigated. The combiner is based on a parallel plate waveguide (PPW) excited with multiple parallel feeds and can be realized using standard PCB technology. The Doherty power combiner scheme can be also integrated in the proposed concept, to increase the efficiency of the amplifiers for implementing amplitude modulation. The advantage of the proposed PPW combiner with respect to other concepts, e.g. the ones based on substrate integrated waveguide (SIW), is the wider bandwidth and the scalability to arbitrarily large number of inputs.
