[linrad] Re: Winrad V0.90



Hi,

FST switches have quite n interesting bandwidth but
switching does not permit to work at 144 or even worst
at 432MHz.

FST3253 maybe OK up to 30 MHz then they may have
internal unbalanced switching. You should see the
conversion loss will increase and also the noise.

FST3125 (3.3V) have been tested OK up to 50 MHz in the
I7SWX 2T H-Mode Mixer with up and down conversion.
