The first switching voltage input unit(330) inputs the first switching voltage, and enables the detector(320) to detect the GSM transmission signal. A GSM transmitting/receiving signal switching unit(340) transmits the GSM transmission signal to the diplexer(310) when inputting the first switching voltage to the input unit(330), and separately outputs the separated GSM receiving signal when not-inputting the voltage.

Abstract: PURPOSE: A structure of a strip line for controlling a frequency of a PLL(Phase Locked Loop) module and a trimming method thereof are provided to generate an accurate frequency from a PLL module by trimming a strip line. CONSTITUTION: Each component of a PLL module is arranged on the same plane as a printed circuit board when the PLL module is formed on the printed circuit board. A strip line structure of the PLL module for controlling a frequency is obtained by forming a strip line layer(S) under the components. A strip line(40) is trimmed until a desired frequency is obtained without removing the casing. A strip line pattern(40) of the strip line layer is processed by trimming the strip line(40). A frequency of the PLL module can be changed by controlling a length of a conductive portion(30) on the PCB substrate(60) of the PLL module through a penetrating hole(50).

Abstract: PURPOSE: A broadband linear amplifier having multiple amplification terminals is provided to generate broadband signals of thousands of MHz needed to realize a broadband wireless communications system. CONSTITUTION: A broadband linear amplifier includes two broadband amplifiers(300,400) and a broadband output matching block(500). The first broadband amplifier(300) amplifies the power from the power supply and generates a signal of tens of MHz having a first gain(G). The second broadband amplifier(400) amplifies once more the amplified output of the first broadband amplifier(300) and produces a broadband signal of tens of MHz having a second gain(G). Thus, amplifying the input signal twice can produce a broadband signal having an adequate gain. And the two broadband amplifiers(300,400) have the same configuration. Each amplifier(300,400) include a frequency characteristic compensation block(302,402), a broadband input matching block(304,404), an amplification block(306,406), a first compensation block(308,408), a second compensation block(310,410), a half wave circuit(312,412) and a twelveth wave circuit(314,414).
