Based on an optimized process layout, ST’s 36 & 50 V LDMOS transistors meet the stringent peak power (>1KW) and ruggedness requirements (>10:1 VSWR) of avionics and radar applications.
The ST air cavity (STAC®) package option features excellent thermal behavior and higher MTTF combined with improved RF performance (enhanced gain and PSAT) compared to ceramic devices.
