Abstract: An RF front-end module includes a transmitting/receiving terminal, a control unit, a first transmitting block and a second transmitting block. The first transmitting block and the second transmitting block connect the transmitting/receiving terminal and the control unit. The control unit controls on or off status of the first transmitting block and the second transmitting block. Thus, the first transmitting block and the second transmitting block can send a signal to the transmitting/receiving terminal directly without pass through any switch unit, avoiding extra signal loss on switch unit.

Abstract: A phase-locked loop (PLL) circuit includes a PLL core circuit, at least one lookup table, and a control circuit. The PLL core circuit generates an output clock under an open-loop calibration phase and a closed-loop calibration phase. The control circuit loads PLL parameters that are derived from the at least one lookup table to the PLL core circuit, performs open-loop calibration upon a first part of the PLL parameters under the open-loop calibration phase of the PLL core circuit, and performs closed-loop calibration upon a second part of the PLL parameters under the closed-loop calibration phase of the PLL core circuit.

Abstract: The present invention relates to a low loss antenna switch. The antenna switch comprises a plurality of switch module and a plurality of transmitting/receiving terminals, wherein one end of each switch module is connected to an antenna unit and the other end of each switch module is connected to each transmitting and receiving end respectively. Further, each switch module comprises a plurality of switch units in series, wherein the width of at least one switch unit is smaller than other switch units of each switch module. Thus, the parasitic capacitance of the off-stage switch modules can be reduced, and VSWR (Voltage Standing Wave Ratio) of the antenna switch also can be improved.

Abstract: A wideband front-end device comprises a wideband amplifying module and a plurality of narrow band filters. The wideband amplifying module comprises an input end, a plurality connecting ends and at least one receiving end. A wideband transmitting RF signal can be transmitted to one of the connecting ends from the input end according to the frequency band thereof. Thus, the wideband transmitting RF signal can be divided into several narrow band signals with different frequency bands. Each narrow band signal with different frequency bands is transmitted to different connecting ends and narrow band filters respectively. Therefore, each narrow band filter can be used to filter wideband transmitting RF signal or narrow band signals with different frequency bands respectively to reduce production costs of the wideband front-end device.

Abstract: The present invention is related to a communication device capable of self-detecting operation status and detecting method thereof. The communication device comprises at least one communication module and a control module. The communication module is capable of self-detecting operation status, so as to generate at least one status information. The control module is allowed to read out the status information of the communication module via a Mobile Industry Processor Interface (MIPI). When the need for the adjustment of operation status of the communication module is diagnosed by the control module, a control signal is generated, and the control signal is transmitted to the communication module via the MIPI, so as to adjust operation status of the communication module. As such, the communication module may be operated under its best status, and also reduce the probability of overheating or abnormal operation.

Abstract: The present invention provides a digital television signal reception system, comprising a chip having a low-noise amplifier and a master receiver, at least one slave receiver, and at least one local-oscillator leakage processing unit. The chip receives at least one digital input signal of television channel. The low-noise amplifier amplifies and sends the input signal of television channel to the master/slave receiver. The input signal of television channel is frequency-mixed by the master/slave receiver so as to output an output signal of second television channel and an output signal of second television channel. The local-oscillator leakage processing unit detects and removes local-oscillator leakage of the master receiver included in the output signal of second television channel, so as to avoid interference of the local leakage of master receiver on sensitivity of receiving the output signal of second television channel of slave receiver by the slave television.
