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.
