Description

The LTC5505-X is an RF power detector for RF applications operating in the 300MHz to 3.5GHz range. A temperature compensated Schottky diode peak detector and buffer amplifier are combined in a small 5-pin ThinSOT 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. A power saving shutdown mode reduces supply current to less than 2?A.The LTC5505-1 operates with input power levels from ?28dBm to 18dBm. The LTC5505-2 operates with input power levels from ?32dBm to 12dBm.Applications Multimode Mobile Phone Products PCS Devices Wireless Data Modems Wireless and Cable Infrastructure RF Power Alarm Envelope Detector
