Atmel has a new Reference Design for their RF Chip. Below is from their News release that I received 2 days back.

New Reference Design for AT86RF211. A new reference design for the AT86RF211 wireless data transceiver is now available. This is a tri-band board: 433, 868 and 915 MHz design, with a single Printed Circuit Board and an adjustable antenna! This makes it possible to build a unique RF platform for many applications worldwide, using the license-free ISM radio spectrum. More than ever, this is an attractive alternative to crowded 2.45 GHz solutions: easy-to-use, 64 Kbits/s, robust and very low cost (BOM = $0.50)! Gerber files are available upon request smartRF@gfo.atmel.com.

How much it cost?
I am afraid it will be too expensive for a RFID tag. Is ther any other cheaper solution on 433.92Mhz?

microchip have such chips, called "rfpic", look at their datasheets.
I am afraid also that the RFID tag working on 13.65Mhz from rfPIC will have a reading distance not up to 2 meters near the metal.

HeiFelix:
The rfPIC is not intended to use as a RFID tag, he also doesn't work at 13.56MHz.

rfPIC is working at 315/433 MHz dependend on the used crystal, F=32xCrystal.

The AT86RF211 is in quantities below 1k ~ 4,50EUR ~ 5$.

Normally I use the CC1000 for robust RF communication, the complete BOM will cost you less then 5,00Euro in low! quantities!!!
I've build a long range "RFID" system on 868MHz, you can get a very low current consumption. Next project will be with a different chip and the half current.
:idea:
