TopBand: Pre amps

[Peter.Chadwick@gpsemi.com (Peter Chadwick)]

Re all the talk about MMICs.

I go along with the idea of a 2N5109 - an excellent transistor.

But DON'T get the idea that a GaAsFET would be worth trying - the 1/f
noise is too high at low frequencies. They're improving all the time,
but still not good enough.
