Foundry Cell Oriented Design of Active Coplanar Power Dividers and Combiners for MMIC Applications

New types of active three ports, based on conventional foundry devices, are presented. Utilising these new devices, active power combiners, dividers and switches may be realised. The modelling of these new type of devices is simply possible by networking individual HEMTs. Measurement and simulation are in excellent agreement. Three different devices will be compared and scaling results are demonstrated. Results of a SPDT-switch are shown. Depending on the device periphery the application frequency may easily go beyond 40GHz.
