Wavice Research Engineer Designs S-Band IMFET
Company
Wavice Inc is a leading defense company in South Korea. It is equipped with an internal fab that provides a durable RF gallium nitride (GaN) process, bolstered by the recent opening of its 0.4 μm foundry service.
Challenge
Long-range radar systems with solid-state power amplifiers (PAs) often require high-power output, and as there is limited installation space, the device must also be very small in size. Monolithic microwave integrated circuits (MMICs) are considered the best solution for reducing the size of PAs, however, the development cost of MMICs can be extremely high when used in low- to medium-volume applications such as defense.
Solution
Wavice Inc designer Kwanjin Oh used the Microwave Office circuit simulator within NI AWR Design Environment platform to design an internally matching field-effect transistor (IMFET) that enabled a size reduction 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.

It would have been impossible to invent the Microlithic mixer without adopting AWR’s Microwave Office simulation technology. By using a modern CAD approach, we successfully condensed four decades of hard-earned mixer design knowledge into 12 months of intense simulation and hardware development. Designing in software has saved us incalculable amounts of time and money.
