AD8361 0.1-2.5GHzRF Microwave True Power Detector AM Detector Amplitude Detection Module

Description AD8361 is a mean response power detector which is suitable for high frequency receiver and transmitter signal chain up to 2 5 GHz The device is very simple to use In most applications only 2 7 V to 5 5 V single power supply power decoupling capacitor and input coupling capacitor can work The output is a linear response DC voltage with a conversion gain of 7 5 V V RMS An external filter capacitor can be added to enhance the average time constant AD8361 is mainly used for real power measurement of simple and complex waveforms especially for peak factor peak to root mean square ratio signals such as CDMA and W CDMA AD8361 has three operating modes which support multiple ADC requirements 1 Grounding mode of reference voltage source with zero source 2 Internal reference voltage source mode can offset the output to 350 mV above the ground level 3 Providing a reference voltage source mode the output can be biased to VS 7 5 Technical parameters 1 Calibrated RMS Response2 Excellent temperature stability3 Input range up to 30 dB 2 5 GHz 4 Maximum input 700 mV rms 10 dBm 50 resistance 5 0 25 dB linear response 2 5 GHz 6 Single power supply 2 7 V to 5 5 V7 Low power consumption 3 3 mW 3 V 8 Fast shutdown mode 1 mu APackage included 1 x RF module
