Been quite busy experimenting with this rf-switch the last couple of days.
There has arrived a lot on and off-list comments regarding rf-switches and I have not had the time to answer all, but thanks.
I am now up in what I call revision 4 switch.
What’s new:
Revised schematics for better RX/bypass-port isolation.
New 10 amps relays.
Have done a lot of λ/4 coax tuning.
TX loss is slightly better.
RX loss is slightly worse.
RX isolation is much better.
What needs to be done:
Switch works but the 75 ohm rg-179 stubs are getting way to hot when passing the Kw level.
Need to find something better.
Revised schematics for better RX/bypass-port isolation.
