LTC5509 300MHz to 3GHz RF Power Detector in SC70 Package

The LTC™5509 is an RF power detector for RF applications operating in the 300MHz to 3GHz range. A temperature compensated Schottky diode peak detector and buffer amplifier are combined in a small SC70 package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3xNiMH.

The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the VOUT pin without gain compression. Consequently, the output voltage is linearly proportional to the RF input voltage. A power saving shutdown mode reduces supply current to less than 2µA.

The LTC5509 operates with input power levels from �30dBm to 6dBm
