looks an interesting component for low cost short range applications
it supports the MiWi protocol which I mentioned in my last post
yes, I was looking at the MRF49XA PICtail Plus Daughter Board which gives some details
**broken link removed**
the MRF49XA is the RF component - you need a microcontroller to drive it
it has an SPI interface, figure 1.2 shows how to connect it to a PIC

you program the PIC with the ICD2
Looking at the specifications they are not compatible (they use different frequencies etc).oooh,okay. can i use rfPIC12F675K as transmitter and MRF49XA as receiver? i think both of the support FSK.

You could use a couple of PICs with MRF49XAs
you could use a low power PIC and the MRF49XA has power saving modes so you only switch it on when transmitting
you need to do the calculations for cost, power consumptions, etc.
e.g. you could use the rfPIC12F675K to talk to a rfRXD0420 receiver connected to a PIC
rfRXD0420
have alook at

I think you need to read thru the application notes for the device, e.g. on page
rfRXD0420
it may be simpler to buy a receiver module

but make sure it will talk to a rfPIC12F675K.
You are getting to a very specialised area, it may be worth putting your questions on the microchip forum
