Device Overview
General Description
The EQ6-26 passive 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 6 dB and a 50-ohm match maintained over the entire operating range.
Features
- 26 Gb/s Equalizer
- Matched 50 Ohm Impedance on Input and Output Ports
Applications
- Signal Integrity
- Digital Communications

Time Domain Performance Plots
Oscilloscope measurements of the EQ6-26 with a 28 Gb/s PRBS pattern. Bit pattern is measured with a 2⁷-1 PRBS input. Eye diagrams are taken with a 2³¹-1 PRBS input. The "Input Data Pattern" figure is uncorrelated with the other patterns due to the additional cable length.
