NGCGXXE0405CM 400 – 450 MHz VFET RF Transistor
The NGCGXXE0405CM SiC RF static induction transistor (SIT) is a normally-on vertical field effect transistor. Each chip contains 5 independent cells which may be wire bonded in parallel to form large power transistors. Up to 10 chips with 50 cells maximum have been successfully combined in one package to form an extremely high power transistor. Each individual cell is capable of 20-40 W pulsed output power depending upon bias and matching conditions.
WPTB32A0912Ax 960-1215 MHz Bipolar RF Transistor
