Integrated combiner with common mode correction

摘要

A circuit can include multiple data input ports and data output ports, pickoff tees coupled therebetween, and a resistive network coupled between the pickoff tees. A differential signal generator can be coupled with the resistive network and the pickoff tees. Resistances of the pickoff tees and resistive network can be selected such that impedances looking into the data input ports and data output ports are matched to a desired system impedance.

1. A circuit, comprising:
a first data input port; a first data output port; a second data input port; a second data output port; a first pickoff tee coupled between the first data input port and the first data output port such that the first data output port is connected to a through output of the first pickoff tee; a second pickoff tee coupled between the second data input port and the second data output port such that the second data output port is connected to a through output of the second pickoff tee; a resistive network coupled between a pickoff output of the first pickoff tee and a pickoff output of the second pickoff tee; and a balun coupled with the resistive network, the pickoff output of the first pickoff tee, and the pickoff output of the second pickoff tee, wherein the first pickoff tee and the second pickoff tee each comprise a passive resistive combiner.
