Hi,
I'm a relative newbie to RF-design, especially when it comes to amplifiers.
Now I need to design an amplifier for the 900MHz range. Goal is to build a linear amplifier which adds about 7dB gain to a 18dBm input signal. I thought by building up a transistor circuit I'll probably learn more than by taking some MiniCircuits MMIC from off the shelf - though I have some probs to find the right transtor for this task. All I know is the 2N2222, which I guess is not the right choice with a gain/bandwidth product of just 300MHz.
I found e.g. a BFG21W, what about that one?
Or are there any other / better transistors fur such an amplifier?
cheers,
rebelde
