ADL5906

Data Sheet ADL5906 10 MHz to 10 GHz, 67 dB TruPwr Detector FEATURES ► Accurate rms-to-dc conversion from 10 MHz to 10 GHz ► Single-ended ±1.0 dB dynamic range: 67 dB at 2.14 GHz ► No balun or external input matching required ► Response independent of waveform types, such as GSM-EDGE/ CDMA/W-CDMA/TD-SCDMA/WiMAX/LTE ► Logarithmic slope: 55 mV/dB ► Temperature stability: <±1 dB from −40°C to +125°C ► Operating temperature: −55°C to +125°C ► Supply voltage: 4.75 V to 5.25 V ► Sleep current: 250 µA ► Pin compatible with ADL5902 and AD8363 APPLICATIONS ► Power amplifier linearization/control loops ► Transmitter signal strength indication (TSSI) ► RF instrumentation GENERAL DESCRIPTION The ADL5906 is a true rms responding power detector that has a 67 dB measurement range when driven with a single-ended 50 Ω source. The easy to use input makes the ADL5906 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 10 GHz. The ADL5906 provides a solution in a variety of high frequency systems requiring an accurate rms measurement of signal power. The ADL5906 can operate from 10 MHz to 10 GHz and can accept inputs from −65 dBm to +8 dBm with varying crest factors and bandwidths, such as GSM-EDGE, CDMA, W-CDMA, TD-SCDMA, WiMAX, and OFDM-based LTE carriers. In addition, its temperature stability over the broad temperature range of −55°C to +125°C makes it ideally suited for a wide array of communications, military, industrial, a...
