特点Temperature Compensated Internal Schottky Diode RF DetectorWide Input Frequency Range: 300MHz to 7GHz*Wide Input Power Range: –32dBm to 10dBmBuffered Detector Output with External Gain Control Precision V OUT Offset Control Low Starting Voltage: 120mV ±35mV for Gain = 2x Wide V CC Range of 2.7V to 6V Low Operating Current: 500μAAvailable in a Low Profile (1mm) SOT-23 Package and Tiny 6-Lead (2mm x 2mm) DFN Package典型应用典型应用描述The LTC?5532 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 V OUT pin.The LTC5532 output buffer gain is set via external resistors. The initial starting voltage of 120mV ±35mV can be precisely adjusted using the V OS pin.The LTC5532 operates with RF input power levels from –32dBm to 10dBm.*Higher frequency operation is achievable with reduced performance.
