Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

I have searched the RF world but can't find any DPDT Switches
for Differential RF Application from 1MHz to 3 GHz. Any recommendations?

What kinds of power levels are you looking for? If not too high,
try researching front-end modules for wireless applications from somebody
like muRata. Some of them still use double-ended I/O.
specs you can provide would help people understand your need better.

Specifications are as follows,
Freq : 1 MHz to 3 GHz
Power Level : 10dBm
Switch : DPDT
RFIC ( not Diversity Switch )
I need to switch differential RF Signals
on my board. I am able to find plenty of SPDT IC, but have not yet come
across DPDT IC.
Macom has DPDT available in die form which is not
much useful. I could use two SPDT but I was hoping that a single DPDT
IC will be better able to match impedance on my board.
