GENERAL DESCRIPTION
The ADL5375 is a broadband quadrature modulator designed for operation from 400 MHz to 6 GHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems. The ADL5375 features a broad baseband bandwidth, along with an output gain flatness that varies no more than 1 dB from 450 MHz to 3.8 GHz. These features, coupled with a broadband output return loss of ≤14 dB, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications, broadband digital predistortion transmitters, and multiband radio designs. The ADL5375 accepts two differential baseband inputs and a single-ended LO. It generates a single-ended 50 Ω output. The two versions offer ……
