The LTC5505-x integrates a temperature compensated Schottky diode peak detector and buffer amplifier in a tiny 1 mm profile 5-lead ThinSOT package. The RF input voltage is peak detected and supplied to the VOUT pin. The LTC5505-1 operates with input power levels from 28 dBm to 18 dBm. The LTC5505-2 operates with lower input power level (higher sensitivity) from 32 dBm to 12 Bm. Each consumes 500 μA of supply current and operates from 2.7 V to 6 V of supply voltage. A power saving shutdown mode reduces supply current to less than 2 μA.
