ADI LTC5532EDC#TRMPBF

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 or (2mm×2mm) DFN package. The supply voltage range is optimized for operation from a single lithium - ion cell or 3×NiMH. 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. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the V₀ₛ pin. The detector operates with RF input power levels from –32dBm to 10dBm.
