Learn More About Equalizers

An RF/Microwave equalizer is a type of filter designed to introduce frequency dependent losses opposite to those naturally present in a system. When inserted into a system with a typical frequency characteristic, it equalizes the broadband insertion loss of the system. Marki equalizers are specific types of high pass filters designed to compensate for typical low pass system characteristics. Important characteristics include the insertion loss at DC, frequency at which the insertion loss is a minimum, return loss, group delay, and rise/fall time. Marki equalizers are suitable for both RF/Microwave and high speed digital data applications. Typical applications include compensation of PCB and cable loss and leveling of gain block amplifiers.


Surface Mounts

Marki surface mount equalizers are designed using a reliable and repeatable GaAs MMIC process, optimized for excellent return loss over their entire operating band. This MEQ family of equalizers provides positive slope from DC to 20GHz with DC attenuation options between 3 and 12.5dB. They are an ideal solution for compensating for low pass filtering effects in RF/microwave and high speed digital systems. All surface mount MEQ equalizers are available in standard 3mm x 3mm QFN packages and connectorized evaluation modules.
