The LTC5533 is a dual channel RF power detector for RF applications operating in the 300MHz to 11GHz range. Two independent temperature compensated Schottky diode peak detectors and buffer amplifiers are combined in a small 4mm × 3mm DFN package.
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.
