I use Microwave Office every day...
if u give me your mail i can give u same templates or give some help for designing your amplifiers..
i have designed lumped and mixed lumped/microstrip low noise, low level amplifiers up to 1GHz....

there are a lot of examples comming with Microwave Office that you can use as a starting point to see how to set-up your amplifier simulations to simulate specific feature. You can start by modifying this examples to suit your problem.
ADS offers step-by-step guide to optimize bias point, gain, etc. and could be a great help if you didn't get the whole picture while studying the aplifier theory.
