PTC4302 ASK RECEIVER MODULE
Description
The PT4302 is an ultra-low power OOK/ASK superheterodyne receiver for the 315/434 MHz
frequency bands. It offers a high level of integration and requires only few external components. The
PT4302 chip 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
ASK/OOK demodulator, an automatic gain control (AGC) loop, a data filter, a slicing comparator and
an on-chip regulator.
The PT4302 is available in 16-pin SSOP package and is specified over the extended temperature
range (¨C40 to +85 ¡ãC).
