     DESCRIPTION
     The PT4301 is a very low power and highly sensitive single chip OOK/ASK super-heterodyne receiver for
the 315MHz and 434MHz frequency bands that 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) limiting 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 -47dBm. The PT4301 is available in a 24-pin SSOP package.

     FEATURES
• Low current consumption (5mA fully active mode at 315MHz)
• 2.4V to 5.5V supply voltage operation range
• Optimized for 315MHz or 434MHz ISM Band
• On-chip image-rejection function
• High dynamic range with on-chip AGC
• Low power down mode current (<1μA)
• High sensitivity of -114dBm (315MHz, 2Kb/s AM 99% square-wave modulation)
• 24-pin SSOP package

    APPLICATIONS
• Remote keyless entry (RKE) systems
• Remote control systems including garage door and gate openers
• Alarm and security systems
• Wireless sensors
