The ADL5903 is a true rms responding power detector that hasa 35 dB measurement range. It features low power consumptionand an intrinsically ripple-free error transfer function.The ADL5903 provides a solution in a variety of high frequencysystems requiring an accurate measurement of signal power.Requiring only a single supply of 3.0 V to 5.0 V and a fewcapacitors, it is easy to use and capable of being driven single-ended or with a balun for differential input drive. An on-chipmatching network provides good return loss over the specifiedfrequency range of the device. The ADL5903 can operate from200 MHz to 6 GHz and can accept inputs from −30 dBm to+20 dBm.The ADL5903 can be used to determine the true power of ahigh frequency signal with a complex modulation envelopeincluding large crest factor signals such as GSM, CDMA,W-CDMA, TD-SCDMA, and LTE modulated signals. Theoutput is then proportional to the logarithm of the rms valueof the input. In other words, the reading is presented directlyin decibels and is scaled about 35.5 mV/dB at 900 MHz.The ADL5903 has low power consumption when operationaland a disable mode that further reduces the power consumption.Power consumption is less than 100 µA when the ADL5903enters power-down mode through a logic low at Pin ENBL.The ADL5903 is supplied in a 2 mm × 2 mm, 8-lead LFCSP foroperation over the wide temperature range of −55°C to +125°C.11769-001516ADL5903RFINENBLRMS COREINTERNALFILTERINGBUFFER630pF1kΩ100Ω4pFVPOS2GND8NICEP4CREG3CRMS7VRMS
