Radio frequency switch and apparatus containing the radio frequency switch
First Claim
1. A radio frequency (RF) switch that switches an input and output of an RF signal, the RF switch comprising:
- a transmission line having one end connected to an input terminal or an output terminal and the other end connected to a signal line, transmission line being configured to transmit the RF signal; and
a diode disposed between the input terminal and the transmission line or between the output terminal and the transmission line, the diode being configured to control whether or not to transmit the RF signal,wherein a CRLH (Composite Right/Left-handed) transmission line is employed as the transmission line.

Abstract
The present invention relates to A radio frequency (RF) switch and an apparatus including the RF switch. In an aspect of the present invention, an RF switch includes a transmission line having one end connected to an input terminal or an output terminal and the other end connected to a signal line and configured to transfer an RF signal, and a diode disposed between the input terminal and the transmission line or between the output terminal and the transmission line, the diode being configured to control whether or not to transmit the RF signal. In another aspect, an RF switch includes a transmission line having one end connected to an input terminal and the other end connected to an output terminal, and a diode disposed between the input terminal and the transmission line or between the output terminal and the transmission line, the diode being configured to control whether or not to transmit the RF signal. Here, a CRLH (Composite Right/Left-Handed) transmission line is employed as the transmission line.
