Driver amplifiers

Driver amplifiers for wireless infrastructure

anchor

Overview

Infineon's wireless infrastructure driver amplifiers can be used as pre-drivers or drivers in RF applications ranging from massive MIMO 5G base stations to small cells and access points. The tiny but mighty amplifiers typically sit between the transceiver IC and the power amplifier, but they can also be used as power amplifiers for low-power applications.

About

High power and high gain

The high driving capability and the high gain allow a minimum number of components in the TX line-up, typically requiring only the pre-driver between the transceiver IC and the power amplifier. In addition, the differential input of the pre-driver saves the balun and converts the differential signal to a single-ended signal without additional losses.

Wide bandwidth and excellent gain flatness

The pre-driver products cover all the relevant frequencies for 5G radios. The excellent gain flatness within these bands enables easy linearization of the subsequent PA without further loading the DPD algorithms.

Low variation over process, voltage, and temperature

The architecture of the devices and special compensation circuits reduce variations of key parameters to a minimum. With that, a stable gain and an optimized level plan in the TX line-up can be achieved.

Internally matched drivers

The drivers are all fully internally matched, reducing the need for externally matched components. This saves cost and enables a more compact design on the PCB.

Driver amplifiers designed for wireless infrastructure

Infineon’s wireless infrastructure driver amplifiers can be used as drivers and pre-drivers in applications like massive MIMO base stations, small cells, repeaters, and satellite communications. Of course, the devices can also be used in all other RF applications that require linear amplification.
