Resolving mMIMO PA Design Challenges

Massive multiple-input-multiple output (mMIMO) system designers are being challenged to improve system efficiency. Balancing wideband linearity with efficiency is a requirement to fit the size, weight, and power requirements of mMIMO systems. View the whitepaper from Wolfspeed and Analog Devices.

RF Power Amplification 101: Amplifier Classes

The purpose of the RF PA is to increase the power of the RF input signal. This is achieved by applying the signal to the gate. This article compares some of the common amplifier classes, starting with the most-linear but least-efficient Class A to the still-linear (due to the ideal transistor) but more-efficient Class F and inverse-F.
