Features & Applications

The MICRF219AYQS is a 3.0 V to 3.6 V QwikRadio Receiver available in 16-Pin QSOP package and its a part of MICRF219A series . It works at a Operating frequency ranging between 300 MHz to 450 MHz.

The MICRF219A functions as a super-heterodyne, image-reject, RF receiver with automatic gain control, ASK/OOK demodulator, analog RSSI output, and integrated squelch features. It only requires a crystal and a minimum number of external components to implement. The MICRF219A is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications.

The MICRF219A achieves -110 dBm sensitivity at a bit rate of 1kbps with 0.1% BER. Four demodulator filter bandwidths are selectable in binary steps from 1625 Hz to 13 kHz at 433.92 MHz, allowing the device to support bit rates up to 20kbps. A shutdown mode reduces supply current to 0.μA typical. The squelch feature decreases the activity on the data output pin until valid bits are detected while maintaining overall receiver sensitivity .

Features:

  • 110 dBm sensitivity at 1kbps with 0.1% BER
  • Auto-polling mode with bit checking
  • Supports bit rates up to 20 kbps at 433.92 MHz
  • 25dB image-reject mixer
  • No IF filter required
  • 60dB analog RSSI output range
  • 3.0 V to 3.6 V supply voltage range
  • 4.3 mA supply current at 315MHz
  • 6.0 mA supply current at 434MHz
  • 13 µA supply current in sleep mode
  • 0.1 µA supply current in shutdown mode
  • 16-pin QSOP package (4.9mm x 6.0mm)
  • −40°C to +105°C temperature range
  • 3 kV HBM ESD Rating
