Airfast Power Amplifier Module with Autobias Control, 3450-3980 MHz, 35 dB, 8 W Avg.

The A5M37SG239 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 and GaN power amplifiers are designed for TDD LTE and 5G systems. The module includes an autobias feature that automatically sets the transistor bias upon power up and an integrated sensor that monitors the temperature. Communications to the module can be accomplished via either I²C or SPI.
