EL SEGUNDO, Calif.
Long-range radar systems with solid-state power amplifiers (PAs) often require high-power output but because there is limited installation space the device must be very small in size. Wavice Inc designer Kwanjin Oh used the Microwave Office circuit simulator within the NI AWR Design Environment platform to design an internally matching field-effect transistor (IMFET) that enabled a reduction in the size of the PA by more than 10 times. Matching the source and drain impedances was straightforward and the load-pull analysis, tuning, and optimization features in the software significantly reduced design time as well.
“NI AWR software is intuitive, which reduced my design time while delivering high accuracy,” said Oh. “In particular, the tuning and optimization features are advantageous for assigning variables to view performance trends.”
