The AD8364 is a wide dynamic range, low power consumption dual channel power detector from ADI. It is designed using an enhanced full digital design, has high accuracy and linearity, can measure high crest factor signals, and has an integrated high precision temperature sensor. It can be used in the temperature range of -40℃~+85℃.
The AD8364 is a true‑RMS, dual‑channel RF power measurement subsystem that provides independent rms outputs for each channel and a differential output. It operates from a single 5 V supply and includes an on‑chip temperature sensor for temperature‑compensated measurements.
Typical applications include wireless infrastructure power‑amplifier linearization, antenna VSWR monitoring, gain and power control, and transmitter signal strength indication. The device offers a wide dynamic range, low log‑conformance ripple, and a small 5 mm × 5 mm LFCSP package.
