The most effective solutions for recovery of impulse signals in dispersing cable lines can be perfomed on the base of heterojunction SiGe BiCMOS technology and are based on combining in one IC high-frequensy analog blocks on heterojunction bipolar transistors and control unit and adaptive correction of parameters on the base of CMOS transistors. Equalizer chip with adaptive correction of parameters provides hidh quality of recovery of signals with smallest costs for tuning and adjustment of cable lines.
