This data sheet introduces the Analog Devices ADL5382 700 MHz to 2.7 GHz quadrature demodulator.
The ADL5382 quadrature demodulator from Analog Devices operates from 700 MHz to 2.7 GHz and provides a single‑supply 4‑5 V design. It delivers a typical voltage conversion gain of about 4 dB, phase accuracy of ~0.2°, and amplitude balance of ~0.05 dB, making it suitable for cellular, Wi‑MAX, and microwave point‑to‑point radios.
The device is supplied in a 24‑lead LFCSP package, features differential RF inputs with 50 Ω impedance, and includes fully buffered I/Q baseband outputs capable of driving 2 V p‑p into 200 Ω loads. Detailed specifications, pin configurations, and typical performance graphs are provided throughout the datasheet.
