PT4317 - PTC

PT4317 Low Power 315/433 MHz OOK/ASK Superheterodyne Receiver

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) limitin.

Features
