DESCRIPTION
The PT4302 is an ultra-low power OOK/ASK super heterodyne receiver for the 315/433.92 MHz frequency bands. It offers a high level of integration and requires only few external components. The PT4302 consists of a low-noise amplifier (LNA), a down-conversion mixer, an on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) and loop filter, an OOK/ASK demodulator, a data filter, a data slicing comparator and an on-chip regulator. The PT4302 also implements a discrete one-step automatic gain control (AGC) that reduces the LNA gain when the RF input signal is greater than –68 dBm. The AGC circuitry can extend the dynamic range of received RF signal.
