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.

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.

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, and instrumentation

applications.

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 ADL5906 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 ADL5906 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.
