Device Overview
General Description
The EQ3-40 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 40 GHz with a DC attenuation value of 3 dB and a 50-ohm match maintained over the entire operating range.
Features
- 40 Gb/s Equalizer
- Matched 50 Ohm Impedance on Input and Output Ports
Applications
- Digital Communications
- Signal Integrity

Time Domain Performance Plots
Oscilloscope measurements of the EQ3-40 with a 40 Gb/s PRBS pattern. Bit pattern is measured with a 2⁷-1 PRBS input. Eye diagrams are taken with a 2³¹-1 PRBS input. Input data pattern figure is uncorrelated with the other patterns due to the additional cable length.
