Features and Benefits
- 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: 550µA
- Low Shutdown Current: <2µA
The LTC5508 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.
