PT4301  
Low Power High Sensitivity 315/434MHz  
OOK/ASK Superheterodyne Receiver  
DESCRIPTION  
FEATURES  
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.  
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
