MICREL SEMICONDUCTOR MICRF007YM

The MICRF007YM is a single chip ON-OFF Keyed (ASK/OOK) QwikRadio Low-power UHF Receiver for remote wireless applications. This device is a true antenna-in to data-out monolithic device. All RF and IF tuning is accomplished automatically within the IC, which eliminates manual tuning and reduces production costs. The result is a highly reliable yet extremely low cost solution. The MICRF007 is a conventional super-heterodyne receiver, with an (internal) local oscillator fixed at a single frequency based on an external reference crystal or clock. As with any conventional super-heterodyne receiver, the companion transmitter's frequency must be accurately controlled, generally with a crystal or SAW (surface acoustic wave) resonator. The MICRF007 requires a mere 2.3mA at 315MHz (3.8mA at 433.92MHz) when fully operational. These features make the MICRF007 ideal for low and ultra-low power applications, such as RKE and RFID.
