The ADL5385-EVALZ is an evaluation board for quick evaluation of ADL5385 quadrature modulator. The ADL5385 is a silicon, monolithic, quadrature modulator designed for use from 30MHz to 2200MHz. Its excellent phase accuracy and amplitude balance enable both high performance intermediate frequency (IF) and direct radio frequency (RF) modulation for communication systems. The AD5385 takes the signals from two differential baseband inputs and modulates them onto two carriers in quadrature with each other. The two internal carriers are derived from a single ended, external local oscillator input signal at twice the frequency as the desired carrier output. The two modulated signals are summed together in a differential to single ended amplifier designed to drive 50ohm loads. The ADL5385 can be used as either an IF or a direct to RF modulator in digital communication systems. The wide baseband input bandwidth allows for either baseband drive or drive from a complex IF.
