Broadside coupled impedance transformers offer the potential for significantly improving the loss and bandwidth of matching networks for high power, broadband power amplifiers. There are currently no adequate scalable models available for prototyping designs. This work presents a novel method for developing an accurate, scalable, process specific, broadside coupler model which can be used to design...
The impedance transformer is an important, but little used, tool for MMIC designers. The Ruthroff style MMIC compatible broadside-coupled impedance transformer has excellent broadband performance, but has an inherent bandwidth limitation due to a half-wavelength resonance in the ground path. A novel but simple method is presented to mitigate the resonance and significantly extend the usable bandwidth...
High voltage, field plate based GaAs MESFETs have great potential for providing high performance MMICs with low cost, high reliability, and immediate production capability required by today's applications. With high voltage operation comes the potential under nonideal operating conditions for premature burnout. Robustness becomes a serious concern for any high voltage application. High Voltage MSAG...
