The ADL5504 is a TruPwr detector with a frequency range of 450 MHz to 6000 MHz. It features true RMS response, excellent temperature stability, and can be used for power measurement of W-CDMA, CDMA2000, QPSK-/QAM-based OFDM, and other applications.
The ADL5504 is a TruPwr™ true‑RMS power detector designed for high‑frequency receiver and transmitter signal chains from 450 MHz to 6 GHz. It operates from a single 2.5 V‑3.3 V supply, draws only 1.8 mA, and provides a linear RMS output voltage.
Key features include excellent temperature stability, a 35 dB dynamic range, 500 Ω input impedance, and a conversion gain of up to 1.87 V/V rms at 900 MHz. The device is RoHS compliant and available in a 6‑ball wafer‑level chip‑scale package.
