Abstract
A method and apparatus for tuning crosstalk and return loss are provided. In the method and apparatus, a filter tunes return loss caused by a first external terminal and a second external terminal to compensate for a capacitive load induced by sizes of and a proximity between the first and second external terminals. The filter decouples the tuning of the return loss from tuning a magnitude and a phase of a crosstalk between a first transmission line network and a second transmission line network such that the return loss is tuned with minimal impact on the crosstalk.
Claims19
An apparatus, comprising:
- a printed circuit board;
- a plurality of external terminals at a first end of the printed circuit board;
- and
- a plurality of internal terminals at a second end of the printed circuit board, the printed circuit board including a filter coupled to a first external terminal and a second external terminal of the plurality of external terminals, the filter including a first inductor coupled between the first external terminal and a first side of a capacitor, and a second inductor coupled between the second external terminal and a second side of the capacitor, the filter being operative to tune return loss caused by the first and second external terminals and help compensate for a capacitive load induced by sizes of and a proximity between the first and second external terminals.

- and
- a filter coupled to a first external terminal and a second external terminal of the plurality of external terminals, the filter including a first inductor coupled between the first external terminal and a first side of a capacitor, and a second inductor coupled between the second external terminal and a second side of the capacitor, the filter being operative to tune return loss caused by the first and second external terminals and help compensate for a capacitive load induced by sizes of and a proximity between the first and second external terminals.
A method comprising:
- tuning, by a filter, return loss caused by a first external terminal and a second external terminal to compensate for a capacitive load induced by sizes of and a proximity between the first and second external terminals, the filter being coupled to the first external terminal and the second external terminal, the filter including a first inductor coupled between the first external terminal and a first side of a capacitor, and a second inductor coupled between the second external terminal and a second side of the capacitor;
- and
- decoupling, using the filter, the tuning of the return loss from tuning a magnitude and a phase of a crosstalk between a first transmission line network and a second transmission line network such that the return loss is tuned with minimal impact on the crosstalk, the first transmission line network including a first transmission line and a second transmission line, the first transmission line being coupled between the first side of the capacitor and a first internal terminal and the second transmission line being coupled between the second side of the capacitor and a second internal terminal.
