AN RF ANTENNA SWITHCH CIRCUIT, A HIGH-FREQUENCY ANTENNA COMPONENT AND A MOBILE COMMUNICATION DEVICE

摘要

PURPOSE: An RF antenna switch circuit, a high frequency antenna component, and a mobile communication device are provided to reduce the number of switching components by sharing the reduced amount in a trasceiving part. CONSTITUTION: One or more transmission switch blocks(10) transfer signal to a common node(4) by a control signal. The transmission blocks are placed in a transmission path between one or more transmitter(2) and the common node. One or more reception switch blocks(30) transfers the signal of the common node to each receiver(3) by the control signal. The reception switch blocks are placed in a reception path between the receiver and the common node. A common switch block(50) is synchronized with each turn on operation of the reception switch and the transmission switch block.
