GaAs monolithic Lange and Wilkinson couplers
Abstract
A monolithic GaAs X-band three-port Wilkinson coupler and a monolithic GaAs X-band four-port interdigitated Lange coupler are examined with reference to their design, fabrication technology, and experimental performance data. It is shown that fabrication of these couplers is compatible with present MMIC technologies. Measured loss minus fixture contributions is 0.25 dB and 0.75 dB for the Wilkinson and the Lange couplers, respectively.
