Absolutely agreed -- it would be better, especially with a couple of these switches in series for higher isolation.

I have not tried it because of the difficulty (for me) of building / designing appropriate PCBs for 75ohm impedance with F-connectors (the one in the datasheet is for 50ohm with tiny SMA connectors).

I've figured out how to change the microstrip spacings for 75ohm, but am unsure about the other components and about actually manufacturing such a PCB with two (or more) of these circuits.

Thanks
