Microchip | MICRF218AYQS

The MICRF218AYQS is a 3.0 V to 3.6 V QwikRadio Receiver available in 16-Pin QSOP package and its a part of MICRF218 series . It works at a Operating frequency ranging between 300 to 450 MHz.

The MICRF218 functions as a super-heterodyne receiver with user selectable Intermediate Frequency (IF) Bandwidths of 550 kHz or 1500 kHz at 433.92 MHz, making it an excellent solution for use with low-cost SAW-based transmitters or transmitters which use low-cost, medium-grade (~30ppm) crystals. The device requires a single, low-cost crystal to select the proper RF frequency, integrated Automatic Gain Control (AGC), data slicer, and programmable baseband filter bandwidths of 1.6kHz to 13kHz allowing the device to support bit-rates up to 20kbps at 433.92 MHz.

The device also features a low-power shutdown mode where the device consumes 1 mA of supply current.
