The document describes the TruPwr Detector ADL5505 Rev. A, which is a true rms response detector for the frequency range of 450 MHz to 6000 MHz. It features excellent temperature stability, over 35 dB input power dynamic range, 500Ω input impedance, and more.
The ADL5505 TruPwr™ detector provides true RMS measurement for high‑frequency receiver and transmitter chains from 450 MHz to 6 GHz. It operates from a single 2.5 V‑3.3 V supply and draws less than 1.8 mA with no input signal.
The device features a 500 Ω nominal input impedance, rail‑to‑rail RMS output with an internal 100 Ω series resistance, and a typical conversion gain of about 1.86 V/V at 900 MHz. It is supplied in a 4‑ball wafer‑level chip‑scale package and is rated for –40 °C to +85 °C operation.
| Frequency range | 450 MHz to 6000 MHz |
