Marki Microwave surface mount RF/microwave active baluns provide single-ended-to-differential conversion (and vice versa) with excellent phase and amplitude balance, high common-mode rejection, and operation extending down to DC. Depending on the part, the active topology can provide gain to compensate for conversion loss, deliver a lossless conversion, or enable DC-coupled operation. They are widely used in receiver front ends, ADC drivers, and differential signal generation for high-speed data converters.
