LTC5508 - 300MHz to 7GHz RF Power Detector with Buffered Output in SC70 Package

The LTC®5508 is an RF power detector for RF applications operating in the 300MHz to 7GHz 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. A power saving shutdown mode reduces supply current to less than 2µA.

The LTC5508 operates with input power levels from -32dBm to 12dBm.

特点 Temperature Compensated Internal Schottky Diode RF Detector Wide Input Frequency Range: 300MHz to 7GHz Wide Input Power Range: –32dBm to 12dBm Buffered Detector Output Wide VCC Range of 2.7V to 6V Low Operating Current: 550mA Low Shutdown Current: <2mA SC70 Package 典型应用
