    Abstract: PURPOSE: A multi-band high frequency switch module is provided to be suitably used for a dual-band mobile phone and contribute to reduce a size of the dual-band mobile phone by being formed as a small chip with a stacked structure. CONSTITUTION: The first switch circuit(SW1) switches a transmitter(TX1) and a receiver(RX1) of the first transmitting/receiving system(GSM(Global System for Mobile communication)). The first low-pass filter circuit(LPF1) is connected to the first switch circuit(SW1). The first transmission terminal(TT1) connects the transmitter(TX1). The second switch circuit(SW2) switches a transmitter(TX2) and a receiver(RX2) of the second transmitting/receiving system(DCS(Digital Cellular System) 1800). The second low-pass filter circuit(LPF2) is connected to the second switch circuit(SW2). The second transmission terminal(TT2) connects the transmitter(TX2). A band splitter circuit(2) splits a band of a communication signal to each transmitting/receiving system.

    Abstract: A printed circuit board and a liquid crystal display device with the same are provided to prevent distortion of an image displayed on a liquid crystal panel and an afterimage. A printed circuit board includes a substrate, a boosting circuit, a feedback voltage generation circuit(220), and a pulse signal wire(240). A boosting circuit formation region(210_a) and a feedback voltage generation region(220_a) are defined on the substrate. The boosting circuit is installed on the boosting circuit region, and boosts an input voltage to generate an analog voltage and a pulse signal. The feedback voltage generation circuit is installed on the feedback voltage generation region, and provides a feedback voltage to a control chip by using the analog voltage. The pulse signal wire outputs the pulse signal and is spaced apart from the feedback voltage generation circuit.
