polyfet rf devices GX242 General Description Polyfet's GAN (on SiC) HEMT power transistors contain no internal matching; making them suitable for both broadband and narrow band applications. The use of a thermally enhanced package enables this device to have superior heat dissipation properties. The high drain break down voltage permits this device to operate over a wide voltage range of up to 50V.
