Microchip | MICRF221AYQS

The MICRF221AYQS is a 3.3 V QwikRadio Receiver available in 16-Pin QSOP package and its a part of MICRF221 series . It works at a Operating frequency ranging between 850 MHz to 950 MHz.

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. This 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 .
