GENERAL DESCRIPTION

The AD8363 is a true rms responding power detector that can be directly driven with a single-ended 50 Ω source. This feature makes the AD8363 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 6 GHz.
The AD8363 provides an accurate power measurement, independent of waveform, for a variety of high frequency communication and instrumentation systems. Requiring only a single supply of 5 V and a few capacitors, it is easy to use and provides high measurement accuracy. The AD8363 can operate from arbitrarily low frequencies to 6 GHz and can accept inputs that have rms values from less than −50 dBm to at least 0 dBm, with large crest factors exceeding the requirements for accurate measurement of WiMAX, CDMA, W-CDMA, TD-SCDMA, multicarrier GSM, and LTE signals.
The AD8363 can determine the true power of a high frequency signal having a complex low frequency modulation envelope, or it can be used as a simple low frequency rms voltmeter. The high­pass corner generated by its internal offset-nulling loop can be lowered by a capacitor added on the CHPF pin.
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. The reading is presented directly in decibels and is conveniently scaled to 52 mV/dB, or approximately 1 V per decade; however, 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 AD8363 has 1.5 mW power consumption when powered down by a logic high applied to the TCM2/PWDN pin. It powers up within about 30 µs to its nominal operating current of 60 mA at 25°C. The AD8363
is available in a 4 mm × 4 mm 16-lead LFCSP
for operation over the −40°C to +125°C temperature range. A fully populated RoHS-compliant evaluation board is also
available.

1 TCM2/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.
2 CHPF
Connect this pin to VPOS via a capacitor to determine the −3 dB point of the input signal high-pass filter. Only add a capacitor when operating at frequencies below 10 MHz.

stability and response time. Minimum C Output Pin in Measurement Mode (Error Amplifier Output). In measurement mode, this pin
is connected to VSET. This pin can be used to drive a gain control when the device is used in controller mode.
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 VSET reduces the gain by approximately 1 dB. 8 TEMP Temperature Sensor Output. See Figure 35 11 VREF General-Purpose Reference Voltage Output of 2.3 V. See Figure 36 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. 13 NC No Connect. N/A 14 INHI
This is the RF input pin for frequencies up to and including 2.6 GHz. The RF input signal is
normally ac-coupled to this pin through a coupling capacitor. 15 INLO
This is the RF input pin for frequencies above 2.6 GHz. The RF input signal is normally ac-coupled
to this pin through a coupling capacitor. 16 TCM1
