Embodiment approach

[0042] Another exemplary embodiment of the present invention is described. When any one of the transmitting switch group 10 and the receiving switch group 30 is in the on state, the shunt switch group that is shunted connected to it so as to be in parallel with it is in the off state, and the rest are not shunted with it The connected shunt switch groups are synchronized with each other and thus operate in a conductive state.

[0043] In one example, the number of switching elements (for example, transistors) of the transmitter-side shunt switch group 20 shunt-connected to each other at the transmitter end 2 may be configured to be greater than that of the receiver-side shunt switch group shunt-connected at the receiver end 3 40 switching elements. In this case, the power transfer capability of the transmission path can be further improved.

[0044] Next, we will refer to figure 1 A common shunt switch bank 60 is described.

[0045] The common shunt switch group 60 is conne...

Abstract

An RF antenna switch circuit, a high-frequency antenna component, and a mobile communication device are provided to reduce the number of parts for configuring the switch. CONSTITUTION: One or more transmission switch blocks transfer signal by a control signal. One or more reception switch blocks transfer signal by a control signal. One or more transmitter-sided shunt switch blocks are connected to each end of one or more transmitters. One or more receiver-sided shunt switch blocks are connected to each end of one or more reception end. A common shut switch block is synchronized with each turn on operation of the shunt switch block.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2011-0071534, filed Jul. 19, 2011, entitled "RF Antenna Switching Circuit, High-Frequency Antenna Component, and Mobile Communication Device," the entirety of which is incorporated by reference at this application. technical field [0003] The present invention relates to an RF antenna switch circuit, a high frequency antenna part and a mobile communication device. More particularly, the present invention relates to an RF antenna switch circuit, a high frequency antenna component and a mobile communication device including a common shunt switch bank. Background technique [0004] In a highly information-oriented society, the use of various types of mobile communication devices has been increasing. While improving communication performance and mobility, various mobile communication devices need to be miniaturized. [0005] Therefore, to support m...
