[AMPS] High isolation RF amplifers.

[Dave Kirkby]

Does anyone know how one goes about designing a wide-band RF amplifer
(small signal, say +10 dBm max output) that has high isolation between
output and input (ie |S12| is small) ??

Whilst I could easily to this for a narrow band amp, I'm intrigued how
companies like Minicircuits can do it for wide band amps. Any ideas ????

The only way I can think of would be to amplify, then attenuate, then
amplify again. I'm just intrigued if there is a better way.
