Microchip | MICRF219AYQS

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 .
