RR8-XXX
3V Supply Voltage - Very Low Consumption
Super Regenerative Radio Receiver
General description
The RR8-XXX is a super regenerative data receiver.
Sensitivity typically exceedes -90dBm when matched
to 50 ohm.
Typical current consumption is 0.5 mA.
Low Turn-on Time (150 msec).
It shows high frequency stability also in presence of
mechanical vibrations, manual handling and in a wide
range of temperature.
The frequency accuracy is very high thanks to laser
trimming process. PATENTED.
XXX: custom-specified working frequency
(200 ÷ 450 MHz)
Standard European and U.S. frequencies (315MHz,
418MHz, 433.92MHz) are readly available from
stock.
