LTC5533 - 300MHz to 11GHz Precision Dual RF Power Detector

The RF input voltage is peak detected using on-chip Schottky diodes. The detected voltage is buffered and supplied to the VOUT pins. A power saving shutdown mode reduces current to less than 2µA/channel. The initial output starting voltages can be precisely adjusted using the VOS pins.

The LTC5533 operates with input power levels from -32dBm to 12dBm.

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