A new reference design has been unveiled for a GaN power amplifier (PA) MMIC for use in X-band active phased array radar applications. The unit, which has a die size of just 1.5 x 2mm, covers 9.0 to 11.5 GHz and delivers 7W (+38.5 dBm) of RF output power from a +29 dBm input, with a PAE of 42%. This means it can be driven by readily available GaAs parts when used as the output PA stage.
