UHF ASK/FSK Receiver ICs
Atmel® Corporation announces the availability of the ATA5745 and ATA5746 UHF ASK/FSK receiver ICs. The ATA5745 operates at 433 to 435 MHz, whereas the ATA5746 covers the 313 to 315 MHz frequency band for the standard automotive environment. These single-chip devices are manufactured using Atmel's RF BiCMOS process UHF6S, enabling even smaller designs. With a size of 5 × 5 mm, they provide one of the industry's smallest footprints, a perfect fit for Remote Keyless Entry (RKE) and Tire Pressure Monitoring System (TPMS) applications. These devices provide a combination of large bandwidth and good receiving selectivity due to their fully-integrated filters.
