MEQ3-26ABH_Passive GaAs MMIC 3 dB DC to 26.5 GHz Equalizer

Device Overview

General Description

The MEQ3-26ABH passive MMIC equalizer is an ideal solution for compensating for low pass filtering effects in RF/microwave and high speed digital systems. This equalizer provides positive slope from DC to 26.5 GHz with a DC attenuation value of 3 dB and a 50-ohm match maintained over the entire operating range. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low cost form factor. The MEQ3-26ABH is available in a SMA connectorized housing. For wire-bondable die, refer to MEQ3-30ACH.
