Airfast Power Amplifier Module with Autobias Control, 3600-4000 MHz, 28 dB, 8 W Avg

The A3M38SL039 is a fully integrated Doherty power amplifier module designed

for wireless infrastructure applications that demand high performance in the

smallest footprint. Ideal for applications in massive MIMO systems, outdoor

small cells and low power remote radio heads. The field-proven LDMOS power

amplifiers are designed for TDD LTE and 5G systems.

The module integrates an

autobias feature with the option to overwrite production settings. Autobias

automatically sets and regulates transistor bias over temperature upon power

up. An integrated sensor for monitoring temperature is also present. Communications to the module can be accomplished via I²C.
