Abstract
Provided is a Single Pole N Throw (SPNT) switch including: a transmission line unit including a plurality of transmission lines each connected between a plurality of selection terminals and a single common terminal; and a SPST switch unit including a plurality of SPST switches for grounding each of the plurality of transmission lines, wherein the SPST switches allows at least a part of the plurality of transmission lines and other transmission lines to operate as open nodes at the common terminal for different frequencies.
Claims6
A Single Pole N Throw (SPNT) switch comprising:
- a transmission line (TL) unit including a plurality of transmission lines each connected between a plurality of selection terminals and a single common terminal;
- and
- a SPST switch unit inducing a plurality of SPST switches for grounding each of the plurality of transmission lines,
- wherein the SPST switch unit comprises a plurality of SPST switches connectable to different locations of each transmission line,
- wherein the SPST switch unit allows the plurality of transmission lines to operate as open nodes at the common terminal for different frequencies by selectively connecting some of the SPST switches on each transmission line.
A SPNT switch matrix in which common terminals of SPNT switches having a plurality of selection terminals and a single common terminal are connected to each other,
- wherein a Single Pole N Throw (SPNT) switch comprises:
- a transmission line unit including a plurality of transmission lines each connected between the plurality of selection terminals and the single common terminal;
- and
- a SPST switch unit including a plurality of SPST switches for grounding each of the plurality of transmission lines,
- wherein the SPST switch unit comprises a plurality of SPST switches connectable to different locations of each transmission lines,
- wherein the SPST switch unit allows the plurality of transmission lines to operate as open nodes at the common terminal for different frequencies by selectively connecting some of the SPST switches on each transmission line.
A transmitter and receiver system including a transmitting antenna and a receiving antenna, which are connected to each of common terminals of different SPNT switches having a plurality of selection terminals and a single common terminal,
- wherein a Single Pole N Throw (SPNT) switch comprises:
- a transmission line unit including a plurality of transmission lines each connected between the plurality of selection terminals and the single common terminal;
- and
- a SPST switch unit including a plurality of SPST switches for grounding each of the plurality of transmission lines,
- wherein the SPST switch unit comprises a plurality of SPST switches connectable to different locations of each transmission lines,
- wherein the SPST switch unit allows the plurality of transmission lines to operate as open nodes at the common terminal for different frequencies by selectively connecting some of the SPST switches on each transmission line.
