Hello I would like to build a multichannel(about 4-5 channels) IR/RFswitch

Can anyone post any schematic? I want i to be simple but to work well.

10x in advance.

 

Have a look at my IR PIC tutorial in the link below.

There are basically two ways of doing it, first with a micro-controller (like a PIC), or with a custom IC (which is probably just a preprogrammed micro-controller) - Holtek make them.
