PT4316 - PTC

PT4316 Low Power 315/433 MHz OOK/ASK Superheterodyne Receiver

The PT4316 is a very low power consumption single chip OOK/ASK superheterodyne receiver for the 315 MHz and 434 MHz frequency bands, which offers a high level of integration and requires few external components. The PT4316 consists of a low-noise amplifier (LNA), mixer, SAW-based local oscillator, on-chip Sallen-Key low-pass filter, intermediate frequency (I.
