GaN RF MOSFET for broadband driver and final stages
The NXP A3G26D055NT4 is a GaN RF power transistor in a 6-LDFN exposed-pad package, delivering 8 W output power at 48 V with 13.9 dB gain across 100 MHz to 2.69 GHz. It targets cellular infrastructure, broadband amplifiers, and ISM-band transmitters where GaN efficiency and bandwidth outperform LDMOS.
Key parametrics for RF design
Rated drain-source voltage is 125 V, providing headroom above the 48 V test rail for load mismatch and peak envelope excursions. The 40 mA quiescent current sets the class-AB bias point for linearity.
