Hi,
Looking for cheap RF IC's for data acquisition. Transmit/receive just a
few bits (20 or less) at time
no faster than 20 or so times a second.
Thanks in advance for any responses.

They make single chip solutions for remote controls and
car lock/unlock. The come in transmit, receive, and transciever
version.

Try googling for >ISM FSK< or ASK. That should find a few
chips and you can then try the manfacturers main web stuff
to find the rest of their offerings.

I don't know what has changed the past few years, but in mass produced RF
remotes and their receivers, the transmitter is built with discretes, with
the antenna on the PCB. The chip only produces the data ro be trasnmitted.
The receiver also has a discrete tuned circuit (also with PCB based
resonant circuits), with an LM324 or LM358 as a data detector.

Here is an example of the sort of stuff I was thinking of:
