DPDT RF Switches - RF Cafe Forums

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 Facebook 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?

Greetings picasso:

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.

Any other specs you can provide would help people understand your need better.

Hello Kirt,
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.
