Hi Lorandt,

do you also have wireless LAN and BT cables?

We have an urgent need of them

Because all this application are WIRELESS make no sense to use a cable ;-)

Sorry to bother you but I can't find any forms to post my questions on. So if you or anyone can show me the direction of where to go.. What I'm trying to build is a (RF) digital band-pass filter. I can't find any schematic's all I could find was equations to find resident freq.. What I'm trying to build is a device that you put in a number between 100Mhz and 800Mhz or so. That you can very lower and upper number digitally.

Any help would be appreciated,
Rob

Hello Ashish Srivastav, I am verry sorry but such power is out of our limits. We do not have any transformer or chokes which could handle such power right now. Our high current version inductors do not exceed 20~30µH and I guess this would not fit to your request. Our High Voltage inductors do not get over few hundert mA. This request is too special and can't be done using standard products. Did you try at TI or LT if they have a solution for the controller?
