Product ID: PT4301

Low Power High Sensitivity 315/434 MHz OOK/ASK Superheterodyne Receiver

The PT4301 is a very low power consumption and high sensitivity single chip OOK/ASK superheterodyne receiver for the 315MHz and 434MHz frequency bands which offers a high level of integration and requires only a few external components. The PT4301 consists of a low-noise amplifier (LNA), an image-rejection mixer, an on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) and loop filter, a 10.7MHz intermediate frequency (IF) lim¬iting amplifier stage with received-signal-strength indicator (RSSI), and analog baseband data recovery circuitry (data filter, peak detector, and data slicer). The PT4301 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 PT4301 is available in 24-pin SSOP package and is specified over the extended temperature range (-40 to +85oC).
