Abstract
An RF power combiner combines the power of several microwave high power FET amplifiers. A plurality of baluns which convert a balanced transmission line to an unbalanced transmission line and have outputs which are 180.degree. out of phase from each other may be connected at the inputs and the outputs of the FETs. This connection allows for very high output power while matching impedances of the input and the output of the power combiner. Additionally, loss in the output circuit can be minimized by connecting equi-phase outputs of the FETs in a parallel/push-pull manner.
