GENERAL DESCRIPTION

The ADL5902 is a true rms responding power detector that has a 65 dB measurement range when driven with a single-ended 50  source. This feature makes the ADL5902 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 9 GHz.

The ADL5902 provides a solution in a variety of high frequency systems requiring an accurate measurement of signal power. 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 ADL5902 can operate from 50 MHz to 9 GHz and can accept inputs from −62 dBm to at least +3 dBm with large crest factors, such as GSM, CDMA, W-CDMA, TD-SCDMA, WiMAX, and LTE modulated signals.

The ADL5902 can determine the true power of a high frequency signal having a complex low frequency modulation envelope or can be used as a simple low frequency rms voltmeter. Used as a power measurement device, VOUT 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 1.06 V per decade, or 53 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 set point. The output buffer can provide high load currents.

The ADL5902 has 1.5 mW power consumption when powered down by a logic high applied to the PWDN pin. It powers up within approximately 5 µs to its nominal operating current of 73 mA at 25°C. The ADL5902 is supplied in a 4 mm × 4 mm, 16-lead LFCSP for operation over the wide temperature range of −40°C to +125°C.

The ADL5902 is also pin-compatible with the AD8363, 50 dB dynamic range TruPwr™ detector. 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.

1 TADJ/PWDN

This is a dual function pin used for controlling the amount of nonlinear intercept temperature compensation at voltages <2.5 V and/or for shutting down the device at voltages >4 V. If the shutdown function is not used, this pin

can be connected to the VREF pin through a voltage divider. See Figure 41 for an equivalent circuit. 2 NC No Connect. Do not connect this pin. 3, 10 VPOS

Supply for the Device. Connect this pin to a 5 V power supply. Pin 3 and Pin 10 are not internally connected;

therefore, both must connect to the source. 4, 9, EPAD COMM

System Common Connection. Connect these pins via low impedance to system common. The exposed paddle

is also COMM and should have both a good thermal and good electrical connection to ground. 5 CLPF

Connection for RMS Averaging Capacitor. Connect a ground-referenced capacitor to this pin. A resistor can be

connected in series with this capacitor to modify loop stability and response time. See Figure 43 for an

equivalent circuit. 6 VOUT

Output. In measurement mode, this pin is connected to VSET. In controller mode, this pin can be used to drive

a gain control element. See Figure 43 for an equivalent circuit. 7 VSET

The voltage applied to this pin sets the decibel value of the required RF input voltage that results in zero

current flow in the loop integrating capacitor pin, CLPF. This pin controls the variable gain amplifier (VGA) gain

such that a 50 mV change in V

changes the gain by approximately 1 dB. See Figure 42 for an equivalent

SET

circuit. 8 TEMP Temperature Sensor Output of 1.4 V at 25°C with a Coefficient of 5 mV/°C. See Figure 38 for an equivalent circuit. 11 VREF General-Purpose Reference Voltage Output of 2.3 V at 25°C. See Figure 39 for an equivalent circuit. 12 VTGT

The voltage applied to this pin determines the target power at the input of the RF squaring circuit. The intercept

voltage is proportional to the voltage applied to this pin. The use of a lower target voltage increases the crest

factor capacity; however, this may affect the system loop response. See Figure 44 for an equivalent circuit. 13 NC No Connect. Do not connect this pin. 14 INHI

RF Input. The RF input signal is normally ac-coupled to this pin through a coupling capacitor. See Figure 37 for

an equivalent circuit.

15 INLO

RF Input Common. This pin is normally ac-coupled to ground through a coupling capacitor. See Figure 37 for

an equivalent circuit. 16 NC No Connect. Do not connect this pin.
