RF Monolithics (RFM) offers a paper, 'Advances in SAW technology', by Darrell L. Ash on its website at www.rfm.com/products/apnotes/lpra.pdf

This paper, first presented at Low Power Radio Association (LPRA) Radio Solutions 99, covers the co-existence of low power radio systems and the Trans European Trunked Radio (TETRA) system. Surface-acoustic-wave (SAW)-based low power receivers and transmitters allow the co-existence of low power radio systems and the TETRA system in the 433 and 868 MHz bands.

SAW filters in the RF front-end of such receivers provide the rejection needed to reduce intermodulation distortion, produced by this high power service, to acceptable levels while providing low insertion loss at the desired frequency and an average 700 kHz 3 dB bandwidth.

This bandwidth accounts for the temperature variations of the SAW-based transmitters and receivers with enough bandwidth left over to allow data rates up to 115 Kbps. These inexpensive, low power consumption SAW transmitters and receivers eliminate the need for PLL frequency synthesizers with their inherent high power consumption, spurious frequencies and fragile crystals.

RFM has recently-introduced a complete SAW-based transceiver, in miniature hybrid form, that is designed to be the basis for low cost two-way short range communications in today's crowded frequency spectrum.
