Loking for RF switch - 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.

Companies i have worked for in the past used big high power RF Switches capable of switching 120KW and more at UHF frequencies what frequency do you need your switch for?

Hello David,

Thank you very much for your reply.
The frequency band we need is 2110~2170MHz.
May I ask you the original Mfg.'s relevant information, and its datasheet? I may need the outline drawing for my design. many thanks!

Best wishes.
