The ADL5505 is a TruPwr™ mean-responding (true rms) powerdetector for use in high frequency receiver and transmitter signalchains from 450 MHz to 6000 MHz. Requiring only a singlesupply between 2.5 V and 3.3 V, the detector draws less than1.8 mA. The input is internally ac-coupled and has a nominalinput impedance of 500 Ω. The rms output is a linear-respondingdc voltage with a conversion gain of 1.86 V/V rms at 900 MHz.The ADL5505 is a highly accurate, easy to use means ofdetermining the rms of complex waveforms. It can be used forpower measurements of both simple and complex waveformsbut is particularly useful for measuring high crest factor (highpeak-to-rms ratio) signals, such as W-CDMA, CDMA2000,WiMAX, WLAN, and LTE waveforms.The on-chip modulation filter provides adequate averaging formost waveforms. An on-chip, 100 Ω series resistance at theoutput, combined with an external shunt capacitor, creates a low-passfilter response that reduces the residual ripple in the dc outputvoltage.The ADL5505 offers excellent temperature stability across a30 dB range and near 0 dB measurement error across temperatureover the top portion of the dynamic range. In addition to itstemperature stability, the ADL5505 offers low process variationsthat further reduce calibration complexity.The power detector operates from −40°C to +85°C and isavailable in an 4-ball, 0.8 mm × 0.8 mm wafer-level chip scalepackage. It is fabricated on a high fT silicon BiCMOS process.
