Features & Applications

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.

Features:

  • Fully integrated 300 to 450 MHz ASK/OOK Receiver
  • No external IF Filter Required
  • Wide IF-Bandwidth filter supports reception of SAW based and medium-grade (~30ppm) transmitter
  • Sensitivity at 433.92 MHz at 1 kbps with 0.1% BER
  • 108 dBm sensitivity with 550 kHz IF Bandwidth
  • 106 dBm sensitivity with 1500 kHz IF Bandwidth
  • Low-Supply Current : 4.0 mA at 315MHz & 5.5 mA at 433.92 MHz
  • 1µA low-power shutdown mode
  • Data Rates to 10 kbps (Manchester Encoded) @ 433.92 MHz
  • Duty Cycling Capable > 100:1 (shut down mode)
  • 60dB Analog Received Signal Strength Indicator
  • 16-pin QSOP (4.9mm x 6.0mm) package
