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. Wavice Inc designer Kwanjin Oh used the Cadence AWR Microwave Office

circuit simulator within the Cadence

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.

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.
