Power Amplifier Design Guidelines
In this article, I have attempted to cover some of the areas which require their own special consideration, and the references quoted at the end are excellent sources of more detailed information on the items where a reference is given.
Power Amplifiers in Bridge Mode
The maximum positive- and negative-voltage capability of a power amp is limited by the power supply's limits, i.e., its voltage rails. The amplifier can produce so many volts positive and negative at its output. The audio signal essentially swings between the positive and negative supplies within the power amplifier.
Biamplification vs. Bridging Power Amplifiers
When seeking more output from a sound system, it is common to bridge the power amplifier to increase the power available and generate more output from the system.

Base Station RF Power Amplifier Biasing
Power amplifiers used in base stations require biasing for proper RF performance. This article explains the two classes of biasing that are prevalent in the RF industry, analyzes their characteristics, and shows implementations with existing ICs.
Amplifier Design Tutorial
This tutorial will set out the design stages required to design a theoretical microwave amplifier with the following specification
Power Amplifier Design for the 2.11GHz 2.17GHz WCDMA band using advanced design system
This application note demonstrates the design of a power amplifier for the 2.11GHz � 2.17 GHz WCDMA band using distributed elements. It features DC simulation, biasing point selection, S-parameter simulation, matching circuit design, optimization, load pull characterization and autolayout.
Balanced Amplifiers
The single amplifier meets the specification for noise figure and again but fails to meet the return loss specification due to the large mis-matches on the input & outputs.
