LTC5533 300MHz to 11GHz Precision Dual RF Power Detector Features - - - - - - - - - - DESCRIPTIO Two Independent Temperature pensated Schottky Diode RF Peak Detectors 45d B Channel-to-Channel Isolation at 2GHz Wide Input Frequency Range: 300MHz to 11GHz- Wide Input Power Range: - 32d Bm to 12d Bm Buffered Detector Outputs with Gain of 2x Adjustable VOUT Starting Voltage Wide VCC Range of 2.7V to 6V Low Operating Current: <500µA/Channel Low Shutdown Current: <2µA/Channel 4mm × 3mm DFN Package The LTC®5533 is a dual channel RF power detector for RF applications operating in the 300MHz to 11GHz range. Two independent temperature pensated Schottky diode peak detectors and buffer amplifiers are bined in a small 4mm × 3mm DFN package. 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. The LTC5533 operates with input power levels from - 32d Bm to 12d Bm. , LTC and LT are registered trademarks of Linear Technology Corporation.
