Description
The WS1A3940 is an Asymmetric Doherty Power Amplifier Module (PAM) integrating Wolfspeed GaN on SiC HEMT transistors with RF
matching and biasing networks on a multilayer laminate substrate with advanced heat sinking technology. The WS1A3940 has been
designed to operate from 3700 MHz to 3980 MHz, from supply voltages up to 50 V, at average output power levels of 8 to 10 W with crestfactor reduced and digitally pre-distorted LTE and 5G NR signals with instantaneous bandwidths of 200 MHz or more. The device is housed
in a 6 mm X 6 mm land grid array (LGA) package.
