Low Power 315/433 MHz OOK/ASK Superheterodyne
Receiver with SAW-based Oscillator
PT4316
DESCRIPTION
The PT4316 is a very low power consumption single chip OOK/ASK superheterodyne receiver for the
315MHz and 434MHz frequency bands and 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 (IF) limiting amplifier stage with
received-signal-strength indicator (RSSI), and analog baseband data recovery circuitry (data filter,
peak detector, and data slicer). The PT4316 also implements a discrete one-step automatic gain
control (AGC) that reduces the LNA gain by 20dB when the RF input signal is greater than -60dBm.
The PT4316 is available in a 16-pin SOP or SSOP package. Both versions are specified over the
extended temperature range (-40℃ to +85℃).
