The TRF1400 VHF/UHF RZ ASK remote control receiver is specifically designed for RZ ASK (return-to-zero amplitude-shift keyed) communications systems operating in the 200-MHz to 450-MHz band. This device is targeted for use in automotive and home security systems, garage door openers, remote utility metering, and other low-power remote control and telemetry systems. A complete RZ ASK receiver solution on a chip, the TRF1400 requires only a minimum of external components for operation. This significantly reduces the complexity and footprint of new designs compared with current discrete receiver designs. The TRF1400 requires no manual alignment when using external SAW (surface acoustic wave) filters. For a lower-cost solution, the device is also compatible with external LC components.
