This datasheet details the features and applications of the ADL5390 RF/IF vector multiplier.
The ADL5390 RF/IF Vector Multiplier consists of a matched pair of broadband variable‑gain amplifiers whose outputs are summed. It provides continuous magnitude control from +5 dB to –30 dB, a wide frequency range of 20 MHz to 2.4 GHz, and low output noise floor, making it suitable for PA linearization, modulation, and RF/IF multiplexing.
The datasheet includes detailed specifications, absolute maximum ratings, pin configuration, typical performance curves, and an ordering guide for the 24‑lead LFCSP package. It also describes recommended usage, ESD precautions, and supply requirements.
