Description

RF RECEIVER 850-950MHZ QSOP-16
The MICRF221 is a third generation QwikRadio® receiver, offering all the benefits of Micrel's earlier QwikRadio® products with significant improvements, including: enhanced sensitivity, automatic duty-cycle feature and RSSI output. The MICRF221 is a super-heterodyne receiver, designed for OOK and ASK modulation. The down- conversion mixer also provides image rejection. The MICRF221 receiver provides a SLEEP Mode for duty-cycle operation and an enhanced, customer programmable "WAKE" function. These features are further combined into a wholly integrated "self-polling" scheme that is ideal for low and ultra-low power applications, such as RKE and RFID All post-detection data filtering is provided on the MICRF221 receiver. Any one of four filter bandwidths may be selected externally by the user in binary steps, from 1.25kHz to 10kHz. The user needs only to program the device with a set of easily determined values based on data rate, code modulation format, and desired duty- cycle operation.
