Driver Amplifiers
Driver amplifiers for wireless infrastructure
The Infineon wireless infrastructure driver amplifiers can be used as pre-drivers or drivers in RF applications from massive MIMO 5G base stations to small cells and access points. The tiny but mighty amplifiers sit typically between transceiver IC and power amplifier but can also be used as power amplifier for low power applications. The driver amplifiers boast high linearity and an excellent wide-band gain flatness for optimum linearization results of the driven PA.

Wireless infrastructure driver amplifiers’ product benefits
Infineon’s wireless infrastructure driver amplifiers offer a wide range of benefits:
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 transceiver IC and power amplifier. In addition, the differential input of the pre-driver saves the balun and converts the differential signal to single-ended without additional losses.
The pre-driver products cover 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.
The architecture of the devices and special compensation circuits reduce variations of key parameters to a minimum. With that a stable gain and optimized level plan in the TX line-up can be achieved.
The drivers are all fully internally matched, reducing the need for external matching components. This saves cost and enables a more compact design on the PCB.
Wireless infrastructure driver amplifiers designs
Infineon’s wireless infrastructure driver amplifiers can be used as drivers and pre-drivers in applications like massive MIMO base stations, small cells, repeaters as well as satellite communications. Of course, the device can also be used in all other RF applications that require linear amplification.
