The ADL5906SCPZN-R7 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 ADL5906SCPZN-R7 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 10 GHz.
The ADL5906SCPZN-R7 provides a solution in a variety of high frequency systems requiring an accurate rms measurement of signal power. The ADL5906SCPZN-R7 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, and instrumentation applications.
Used as a power measurement device, VRMS is connected to VSET. The output is then proportional to the logarithm of the rms value of the input. In other words, the reading is presented directly in decibels and is scaled 1.1 V per decade, or 55 mV/dB; other slopes are easily arranged. In controller mode, the voltage applied to VSET determines the power level required at the input to null the deviation from the setpoint. The output buffer can provide high load currents.
Requiring only a single supply of 5 V and a few capacitors, it is easy to use and capable of being driven single-ended or with a balun for differential input drive. The ADL5906SCPZN-R7 has a low 250 µA sleep current when powered down by a logic high applied to the PWDN pin. It powers up within approximately 1.4 µs to its nominal operating current of 68 mA at 25°C.
The ADL5906SCPZN-R7 is supplied in a 4 mm × 4 mm, 16-lead LFCSP and it is pin compatible with the ADL5902 and the AD8363 TruPwr™ rms detectors. This feature allows the designer to create one circuit layout for projects requiring different dynamic ranges. A fully populated RoHS-compliant evaluation board is available.
