Product Details

The LTC5530 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 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. The output buffer gain is set via external resistors. A power saving shutdown mode reduces current to less than 2µA.

The LTC5530 operates with input power levels from -32dBm to 10dBm.

*Higher frequency operation is achievable with reduced performance. Consult factory for more information.
