Application Scenarios & Design Considerations

315MHz/433MHz ASK Superheterodyne Receiver with Extended Dynamic Range

Alternative Part Number

  • ATA5428C-PLQW --: Sub-GHz ISM transceiver with similar UHF receiver function and SPI interface, suitable as a functional replacement in 433/868 MHz designs.
  • SI4432-B1-FMR --: Widely used sub-GHz transceiver covering 240-930 MHz with comparable sensitivity and low-power operation, a common drop-in alternative for ISM receivers.
  • CC1101RGPR --: Low-power sub-1 GHz RF transceiver with similar frequency range and SPI control, well supported and often used where MAX1473-class receivers are specified.
