Amplifier Design Tutorial
Introduction
This tutorial will set out the design stages required to design a theoretical microwave amplifier with the following specification shown in Table 1:
Table 1 Required Specification
The first stage in the design process is to pick a suitable device. For X-Band and above GaAs MESFETS are used while at lower frequencies Bipolar devices are used if noise is not so critical. Try to pick a device design for the range of frequencies you require. Don’t for example use an X-band device for an LNA at UHF – you are bound to run into stability problems. Also pick a device that will give you plenty of gain margin to allow for noise mismatching etc.
