Description:

The A5M37SG239 is a fully integrated Doherty power amplifier module for wireless infrastructure applications requiring small specifications and high performance. It is suitable for mMIMO systems, outdoor small cells and low power RF remote applications. This mature LDMOS and GaN power amplifier is designed for TDD LTE and 5G systems. The module includes an automatic bias function that automatically sets the transistor bias value when powered on, as well as an integrated sensor that monitors temperature. This module can be communicated via I²C or SPI.


Main features:

Level 2 module solution, including LDMOS integrated circuit as driver and GaN final amplifier

Advanced high performance internal package Doherty

Full match (50Ω input/output, DC blocking)

It is suitable for digital linearization system with low complexity

Reduce the memory effect and improve the linearization error vector amplitude

Automatic bias during power-on

Temperature sensing

Digital interface (I2C or SPI)

Embedded registers and Dacs for setting bias conditions

Tx Enable Control pins are used for TDD operations
