A3M39SL039
Airfast Power Amplifier Module with Autobias Control
Rev. 0 — March 2022
The A3M39SL039 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 and FDD LTE
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 either I
