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 3.5 GHz. These features, coupled with a broadband output return loss of ≤−12 dB, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications,
