RoHS-compliant OUTPUT (V) 1 0.1 Measurement of CDMA-, CDMA2000-, W-CDMA-, and QPSK-/
QAM-based OFDM, and other complex modulation
waveforms
RF transmitter or receiver power measurement 0.03
–25 –20 –15 –10 –5 0 5 10 15 INPUT (dBm) 06056-001 APPLICATIONS Figure 1. Output vs. Input Level, Supply = 3 V, Frequency = 1.9 GHz GENERAL DESCRIPTION
The on-chip, 100 Ω 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. For more
complex waveforms, an external capacitor at the FLTR pin can
be used for supplementary signal demodulation. The ADL5501 is a mean-responding TruPwr™ power detector
for use in high frequency receiver and transmitter signal chains
from 50 MHz to 6 GHz. It is easy to apply, requiring only a single …
