Patent number: 9135940Abstract: A radio frequency (RF) circuit includes a first microchip for transmitting RF signal, a second microchip, two resistors and at least two signal lines. Each signal line has opposite first and second ends, and each first end of each signal line is connected to the first microchip and each second end of each signal line is connected to the second microchip. Each signal line defines first and second gaps, the first gaps are adjacent to the first microchip and the second gaps are adjacent to the second microchip. The two resistors are selectively located at the gaps of any one signal line, whereby the first microchip and the second microchip are connected to each other through the signal line and the resistors to form a connection path.Type: GrantFiled: April 6, 2012Date of Patent: September 15, 2015Assignees: SHENZHEN FUTAIHONG PRECISION INDUSTRY CO., LTD., Chi Mei Communication Systems, Inc.Inventors: Xiao-Dong Wang, Hang Dong, Ya-Nan Chen, Jian-Yan Feng

Patent number: 8543067Abstract: An exemplary embodiment of communication device includes a signal communication module, a first switch module, a processor, a second switch module, and a power amplifying module. The signal communication module, the first switch module, the processor, the second switch module, and the power amplifying module are electrically connected in series. The signal transceiver receives and sends a wireless communication signal. The first switch module and the second switch module are used for switching on corresponding receiving and sending paths of the wireless communication signal under the control of the processor. The power amplifying module is configured for amplifying and adjusting signal strength of the broadcast signal from the second switch module controlled by the processor.Type: GrantFiled: January 27, 2010Date of Patent: September 24, 2013Assignees: Shezhen Futaihong Precision Industry Co., Ltd., Chi Mei Communications Systems, Inc.Inventor: Jian-Yan Feng

Patent number: 8493894Abstract: A radio frequency (RF) front-end circuit includes a multiband antenna, an antenna switch, a duplexer, a communication mode selection switch, and a processor. The processor selectively connects the antenna switch or the duplexer to the multiband antenna using the communication mode selection switch. When the multiband antenna is connected to the antenna switch, the processor directs the antenna switch to transmit wireless signals used in a first wireless communication system received by or sent from the multiband antenna; when the multiband antenna is connected to the duplexer, the duplexer transmits wireless signals used in a second wireless communication system received by or sent from the multiband antenna.Type: GrantFiled: January 22, 2011Date of Patent: July 23, 2013Assignees: Shenzhen Futaihong Precision Industry Co., Ltd., Chi Mei Communication Systems, Inc.Inventor: Jian-Yan Feng
