DESCRIPTION

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 (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 20 dB when the RF input signal is greater than -60 dBm. The PT4316 is available in a 16-pin SOP or SSOP package. Both versions are specified over the extended temperature range (-40℃ to +85℃).
