10-30 GHz monolithic GaAs travelling-wave divider/combiner
Abstract
A four-way monolithic GaAs traveling-wave power divider/combiner has been designed, fabricated and evaluated. With a design center frequency of 20 GHz, a bandwidth of from 10 GHz to 30 GHz has been measured. The insertion loss per dividing or combining action is less than 0.5 dB, with isolation between ports no worse than 20 dB. The input/output VSWRs are better than 2:1 across the same band. This divider/combiner can readily be used with monolithic GaAs power FET amplifiers to produce a several-fold increase in output powers over the 10 to 30 GHz frequency range.
