Description

RECEIVER 3.3V 300~450MHZ 16QSOP
The MICRF218 is a 3.0V to 3.6V, 300MHz to 450MHz ASK/OOK super-heterodyne receiver with user selectable Intermediate Frequency (IF) Bandwidths of 550kHz or 1500kHz at 433.92MHz, 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 433.92MHz. The MICRF218 consumes 4.0mA of supply current at 315MHz and 5.5mA of supply current at 433.92MHz. The device also features a low-power shutdown mode where the device consumes 1µA of supply current. The device achieves a sensitivity of -108dBm at 1kbps. For transmitters using higher-quality (~10ppm) crystals, the MICRF219A/MICRF220 offer an IF-bandwidth of 330kHz and a sensitivity of -110dBm at 1kbps, which can provide better sensitivity and longer range performance.
