The ADL5390 is a RF/IF vector multiplier from Analog Devices with a wide frequency range (20 MHz to 2.4 GHz), continuous magnitude control range (from +5 dB to -30 dB), up to 230 MHz adjustable modulation bandwidth, single supply voltage (4.75 V to 5.25 V), etc. It is mainly used for PA linearization and predistortion, amplitude and phase modulation, variable matched attenuators and/or phase shifters, cellular base stations, radio links, fixed wireless access, broadband/CATV RF/IF analog multiplexers, etc.
The ADL5390 is a broadband RF/IF vector multiplier that combines a matched pair of variable‑gain amplifiers. It supports a frequency range of 20 MHz to 2.4 GHz, continuous magnitude control from +5 dB to –30 dB, and can be configured as a vector modulator, variable attenuator/phase shifter, or 2:1 RF multiplexer.
The document includes detailed specifications, absolute maximum ratings, pin configuration, typical performance curves, and guidance for using the device in PA linearization, cellular base stations, broadband/CATV, and other RF applications. Evaluation boards and ordering information are also provided.
