The ADL5374 is a fixed‑gain quadrature modulator designed for operation from 3000 MHz to 4000 MHz. It provides a single‑ended RF output, accepts differential I/Q baseband inputs, and is supplied from a single 4.75 V to 5.25 V rail. The device is offered in a 24‑lead LFCSP package and is RoHS compliant.
Typical performance includes >500 MHz 3 dB bandwidth, sideband suppression of –50 dBc, carrier feedthrough around –35 dBm, and a 1 dB compression point near 12 dBm. The datasheet also details pin functions, absolute maximum ratings, recommended power‑supply layout, and evaluation‑board options.
