GENERAL DESCRIPTION
The ADL5504 is a TruPwr mean-responding (true rms) power
detector for use in high frequency receiver and transmitter signal
chains from 450 MHz to 6000 MHz. Requiring only a single
supply between 2.5 V and 3.3 V, the detector draws less than
1.8 mA. The input is internally ac-coupled and has a nominal
input impedance of 500 . The rms output is a linear-responding
dc voltage with a conversion gain of 1.87 V/V rms at 900 MHz.
The ADL5504 is a highly accurate, easy to use means of
determining the rms of complex waveforms. It can be used for
power measurements of both simple and complex waveforms
but is particularly useful for measuring high crest factor (high
peak-to-rms ratio) signals, such as W-CDMA, CDMA2000,
WiMAX, WLAN, and LTE waveforms.
The on-chip modulation filter provides adequate averaging for
most waveforms. For more complex waveforms, an external
capacitor at the FLTR pin can be used for supplementary signal
demodulation. An on-chip, 100 series resistance at the output,
combined with an external shunt capacitor, creates a low-pass filter
response that reduces the residual ripple in the dc output voltage.
The ADL5504 offers excellent temperature stability across a
30 dB range and near 0 dB measurement error across temperature
over the top portion of the dynamic range. In addition to its
temperature stability, the ADL5504 offers low process variations
that further reduce calibration complexity.
The power detector operates from 40°C to +85°C and is
available in a 6-ball, 0.8 mm × 1.2 mm, wafer level chip scale
package. It is fabricated on a high fT silicon BiCMOS process.
