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.

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
