Description
AI
The LTC5532 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™or (2mm x 2mm) DFN package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3x NiMH.The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the VOUTpin.The LTC5532 output buffer gain is set via external resistors. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the VOSpin.The LTC5532 operates with RF input power levels from –32dBm to 10dBmApplications802.11a, 802.11b, 802.11g, 802.15Multimode Mobile Phone ProductsOptical Data LinksWireless Data ModemsWireless and Cable InfrastructureRF Power AlarmEnvelope Detector
