David,

Very interesting TX.
Do you have the RX schematic to match that?

David

Here is a schematic for a simple, low cost transmitter.

I have several RX typologies. I think the simplest for you to implement is
to use the micrel MICRF02 IC.
This only needs a crystal and a couple of capacitors.
Check out http://www.micrel.com

<x-rich>what is the output frequency of your transmitter?


Thanks,

Robert

I think the most important here is the PCB layout.
Would you mind to share with us?

Friendly Regards

You determine the frequency by the resonator used. The loop dimensions given
are for 303.8 Mhz

The antenna is a printed track that is 3mm wide and occupies a square with
side lengths of 25mm.

Keep the component lead lengths as short as possible.
Single sided PCB works fine (there must be no earth plane under the loop
antenna). The resonators can be obtained from RFM (http://www.rfm.com) and are
available in surface mount or conventional packaging.
