Design of a vhf class-a amplifier for optimum power output 2013-02-11

Summary
This article presents the design of Class-A VHF transistor amplifier intended to provide as much linear output power as possible. It demonstrates basic design techniques to yield optimum output power from a BFR92A bipolar transistor. The selection of the transistor was conditioned on: (1) availability of SPICE model, and (2) availability of S-parameters.

Analysis
To begin the design a suitable transistor needs to be chosen. For this article the BFR92A from NXP was...
