The WS1A3940-V1 from MACOM is an Asymmetric Doherty Power Amplifier Module (PAM) that operates from 3.70 to 3.98 GHz. It has been designed using GaN on SiC HEMT transistors with advanced matching and biasing networks on a multilayer laminate substrate with advanced heat sinking technology. It provides an output power of 8 to 10 W with crest-factor reduced and digitally pre-distorted LTE and 5G NR signals with instantaneous bandwidths of up to 200 MHz. The amplifier requires a supply voltage of 48 V and is available in an LGA package that measures 6 x 6 mm and is ideal for multi-standard cellular power amplifier applications.
