IGN2729M400R2 is a high power GaN-on-SiC RF power transistor that has been designed to suit the unique needs of modern radar systems. It supplies 400W of peak output power, with typically >18 dB of gain and 63% efficiency. It operates from a 50 V supply voltage. For optimal thermal efficiency, the transistor is housed in a metal-based package with an epoxy-sealed ceramic lid.
