The ADL5371 is a fixed-gain quadrature modulator designed for use from 500 MHz to 1500 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency modulation.
The ADL5371 quadrature modulator from Analog Devices operates from 500 MHz to 1500 MHz and provides a wide 3 dB baseband bandwidth of over 500 MHz. It accepts two differential baseband inputs and a single‑ended LO input, delivering a single‑ended RF output. The device is fabricated in a 24‑lead LFCSP using Analog Devices' silicon‑germanium bipolar process and is specified for –40 °C to +85 °C operation.
Key features include a 14.4 dBm 1 dB compression point, –55 dBc sideband suppression, and a low noise floor of –158.6 dBm/Hz at 915 MHz. The datasheet provides detailed pin configurations, typical performance graphs, and application notes for cellular, WiMAX, cable, and satellite systems.
