New receiver architecture based on SAWs

This paper describes a basically new receiver architecture that has been realized to address short range RF link (primarily in the 200 to 960 MHz UHF band) applications. With no adjustments or critical PC board layouts to contend with, this new SAW-based receiver demonstrates superior range performance compared to conventional receivers. The new receiver operates from a 3 volt lithium button cell with a current drain of approximately 1 mA. The receiver is entirely self-contained, with an RF antenna input port and a CMOS compatible data output port, in a small surface mount package. Unlike other receivers, the new receiver reliably operates in the crowded frequency spectrum of our present day due to outstanding frequency selectivity.
