433MHz RF link for under S10 BOM?

I need to wirelessly enable a device over a 433MHz link, but the cost has to be under S10.... (in quantity of hundreds and above). Here are the main features:

- 100m outdoor coverage area
- Under 1w power
- ISM 433MHz band
- Half-duplex communication

A micro is provided to run the software required for decoding, protocol stack etc (so need not be part of the BOM).

Any suggestions for a chip/module to use?

Have a look at abacom (www.abacom-tech.com) or aurel (www.aurelwireless.com) modules. They surely have what you need.

Thanks RobinH, but these modules are much too expensive. Basically I am talking about creating such a module from scratch, if none can be found for the relevant price.

Have you looked at the AMIS wireless ASSP family?

Thanks RBB, looks interesting.
Do you know what the cost is?
Have you used this chip?

I'm not sure of the cost.
I think the 53050 itself is less than S2, but again I'm not sure.
I also don't know what the total BOM would be with the 53050.
I know a little about it, so if you have any questions feel free to ask.

Looks like the AMIS-53050 is approx. S3 US.
