http://www.nvlsi.no/ Seem to just plug in and use ...except that radio freq design of the PCB is is not very easy. But i guess they have reference designs. I also ting u have seen some post aroundhere about another company selling radio modules with theese chips. The chips are very well documented. Just write in some registers to tell it what to do. I was at a seminar once, and they told they could help with the design too. (I was considering them for a project that got halted.) /Morgan Falcon Wireless Tech Support - KF4HAZ 16:24 2004-07-09: >I have a side project, probably just a one off, where I need a low power >transmitter. >Something around the range 2.5 to 25mw across the spectrum of ~100 to 500 >MHz (does not have to have a flat output power level across the entire >spectrum) >Needs to be capable of about 1.25 to 2.5 KHz deviation (sine wave or >something close, squareish waves would be a plus) in the low audio range. >Transmit frequency needs to be controllable via a micro-controller (again >accuracy not terribly critical but this is the one area that should be >fairly accurate) if I tell it to transmit at 450MHz it should be within 5 or >10KHz of this frequency and reasonably stable. > >KF4HAZ - Lonnie > >-- >http://www.piclist.com hint: To leave the PICList >mailto:piclist-unsubscribe-request@mitvma.mit.edu -- Morgan Olsson, Kivik, Sweden -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
