Radio Receiver telecontrolli 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.
