The LTC5536 is an RF power detector for RF applications operating in the 600MHz to 7GHz range. A temperature compensated Schottky diode peak detector and fast comparator are combined in a small ThinSOT™package. The supply voltage range is optimized for operation from a single cell lithium-ion or three cell NiMH battery.The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is compared against a reference voltage at VM.The response time from the RF input to VOUTcan be as little as 20ns. The comparator output is latched when LEN is high or is transparent when LEN is low.The LTC5536 operates with RF input power levels from –26dBm to 12dBm.ApplicationsRF Signal Presence Detectors for:802.11a, 802.11b, 802.11g, 802.15Optical Data LinksWireless Data ModemsWireless and Cable InfrastructureRF Power AlarmEnvelope DetectorRF ID Tag Reader

The LTC5540 is part of a family of high dynamic range, high gain passive downconverting mixers covering the 600MHz to 4GHz frequency range. The LTC5540 is optimized for 0.6GHz to 1.3GHz RF applications. The LO frequency must fall within the 0.7GHz to 1.2GHz range for optimum performance. A typical application is a LTE or GSM receiver with a 700MHz to 915MHz RF input and high-side LO.The LTC5540 is designed for 3.3V operation, however; the IF amplifier can be powered by 5V for the highest P1dB. An integrated SPDT LO switch with fast switching accepts two active LO signals, while providing high isolation.The LTC5540’s high conversion gain and high dynamic range enable the use of lossy IF filters in high-selectivity receiver designs, while minimizing the total solution cost, board space and system-level variation.ApplicationsWireless Infrastructure Receivers (LTE, GSM, W-CDMA)Point-to-Point Microwave linksHigh Dynamic Range Downmixer Applications
