PTC PT4317
The PT4317 is a low power single chip OOK/ASK superheterodyne receiver for the 315MHz and 434MHz frequency bands that offers a high level of integration and requires few external components. The PT4317 consists of a low-noise amplifier (LNA), down-conversion mixer, SAW-based local oscillator, on-chip gm-C band-pass filter, intermediate frequency (IF) limiting amplifier stage with received-signalstrength indicator (RSSI), and analog baseband data recovery circuitry (data filter, peak detector, and data slicer). The PT4317 is available in a 16-pin SSOP package.| Part No. | PT4317 |
