LTC5532EDC#TRMPBF

LTC®5532 is an RF power detector for applications operating from 300KHz to 7MHz. 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. This output buffer gain is set via external resistors. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the VOS pin. Application includes 802.11a, 802.11b, 802.11g, 802.15, multimode mobile phone products, optical data links, wireless data modems, wireless and cable infrastructure, RF power alarm, envelope detector.
