Device Overview
General Description
The MEQ4-70ACH passive MMIC equalizer die is an ideal solution for compensating for low pass filtering effects in RF/microwave and high speed digital systems. It provides positive slope from DC to 70 GHz with 4 dB DC attenuation. The unique design offers superior return loss to competitors. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low cost form factor.
