Superheterodyne Receiver<br />
<strong>RRQ3</strong>-<strong>XXX</strong><br />
AM Superhet Receiver with Crystal Oscillator<br />
and Squelch Circuit<br />
General description<br />
The <strong>RRQ3</strong>-<strong>XXX</strong> is an AM superhet data receiver<br />
with PLL synthesizer and crystal oscillator.<br />
A squelch function is implemented to reduce output<br />
"noise" when no transmitter is active.<br />
Receiver Frequency: 315 / 433.92 / 868.35 MHz<br />
IF Frequency: 10.7MHz<br />
Typical sensitivity: -106 dBm<br />
Supply current: 5 mA (typ)<br />
