Low Power High Sensitivity 315/434 MHz OOK/ASK
Superheterodyne Receiver
Preliminary
PT4301
DESCRIPTION
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) 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 -60dBm. The
PT4301 is available in 24-pin SSOP package and is specified over the extended temperature range
(-40 to +85oC).
FEATURES
• Low current consumption (5mA fully active mode at 315MHz)
• 2.4 to 5.5V supply voltage operation range
• Optimized for 315 or 434MHz ISM Band
• On-chip image-rejection function
• High dynamic range with on-chip AGC
• Power down mode with very low supply current (<1µA)
• High sensitivity of -114dBm (2Kb/s AM 99% square-wave modulation, 315MHz)
• Low external parts count
• 24-pin SSOP package
APPLICATIONS
www.•DataRSehemet4oUte.cokmeyless entry (RKE) systems
• Remote control systems including garage door and gate openers
• Alarm and security systems
• Wireless sensors
