MICRF005

MICRF005 Micrel MICRF005 115kbps, 800MHz - 1GHz UHF Receiver Final Information General Description The MICRF005 QwikRadio™ UHF receiver is a single-chip OOK (on-off keyed) receiver IC for remote wireless applications. This device is a true single-chip, “antenna-in, data-out” device. All RF and IF tuning is accomplished automatically within the IC which eliminates manual tuning production costs and results in a highly reliable, extremely low-cost solution for high-volume wireless applications. The MICRF005 provides two additional key features: (1) A transmit standby mode, and (2) a shutdown mode which may be used for duty-cycle operation. These features make the MICRF005 ideal for low power applications in both one-way and bi-directional wireless links. All IF and post-detection (demodulator) data filtering is provided on the MICRF005, no external filters are required. Nominal filter bandwidth is fixed a 300kHz allowing a data throughput at rates up to 115kbps. Features 800MHz to 1000MHz frequency range Data rates up to 115kbps No filters or inductors required Low 10mA operating supply current at 868MHz Shutdown mode for >10:1 duty-cycle operation Very low RF antenna re-radiation CMOS logic interface for standard ICs Extremely low external part count Transmit standby mode for bi-directional link control Applications Wireless game controllers Security systems Medium-rate data modems Ordering Information Part Number MICRF005BM Junction Temp.
