SL6654
LOWER POWER IF/AF CIRCUIT (WITH RSSI) FOR FM CELLULAR RADIO
The SL6654 is a complete single chip mixer/oscillator, IF
amplifier and detector for FM cellular radio, cordless
telephones and low power radio applications. It features an
exceptionally stable RSSI (Received Signal Strength
Indicator) output using a unique system of detection. Supply
current is less than 2mA from a supply voltage in the range
2.5V to 7.5V.
