Features

  • Low cost single conversion superheterodyne receiver architecture.
  • Compatible with rfPIC™ and rfHCS series of RF transmitters.
  • Easy interface to PICmicro® microcontroller (MCU) and KEELOQ® decoders.
  • VCO phase locked to quartz crystal reference: - Narrow receiver bandwidth - Maximizes range and interference immunity.
  • Selectable LNA gain control for improved dynamic range.
  • Selectable IF bandwidth via external ceramic IF filter.
  • Receiv.
