LTC5533EDE#PBF

LTC5533 is a dual channel RF power detector for RF applications operating in the 300MHz to 11GHz range. 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. It is used in applications such as PA forward and reverse power monitor, dual PA transmit power control, 802.11a, b, g, 802.15, WiMAX, PA linearization, fixed wireless access, RF power alarm, envelope detector etc.
