    Abstract: PURPOSE: A wideband low noise amplifier is provided to improve a noise property by reducing a noise index and facilitate an ultra wideband input matching. CONSTITUTION: A common gate amplifier(110) amplifies an input signal inputted to an input terminal and outputs the amplified signal to an output terminal. A cascade amplifier(120) amplifies the output voltage of the common gate amplifier inputted to the input terminal and outputs the amplified voltage to the output terminal. A source following buffer(130) outputs the output voltage of the cascade amplifier inputted to the input terminal to reduce signal attenuation.

    Abstract: PURPOSE: A transmission and reception apparatus and method thereof are provided to create discontinuous interference signals by embodying variable data throughout without controlling a modulation parameter. CONSTITUTION: A data rate control unit outputs input data bit strings to a group unit according to target data rates(S710). The group unit groups the inputted data bit strings(S720). A first modulation unit modulates a part bit of a group in a FSK(Frequency Shift Keying) modulation method based on duty(S730). A second modulation unit modulates the other bits in PSK(Phase Shift Keying) modulation method(S740). A signal transmission unit creates transmission signals(S750).

    Abstract: PURPOSE: A wake-up signal communication system, apparatus, method, and wireless terminal are provided to increase the number of wake-up target wireless terminals wake-up signal transmission distances and coverage by using a center wake-up system. CONSTITUTION: A detector(340) creates signals rectified by the rectification of a first wake-up signal. A code generation apparatus(350) outputs code signals corresponding to codes of a wake-up target terminal. A comparator(360) creates a second wake-up signal transmitted to the wake-up target terminal by using the rectified signal and the code signal. The rectified signal is inputted to a non-inverting terminal of the comparator.

    Abstract: PURPOSE: An apparatus and a method for reducing a leakage signal are provided to remove the leakage signal from a third frequency signal outputted from a frequency converter using a first frequency signal outputted from a local oscillator. CONSTITUTION: A local oscillator(101) generates a first frequency signal. A divider(102) generates a second frequency by dividing the first frequency signal. A frequency converter(103) generates a third frequency signal using the first and second frequency signals. A variable phase shifter(104) adjusts the phase of the first frequency signal. A variable gain amplifier(105) adjusts the gain of the output signal of the variable phase shifter. An operator(106) operates the output signal of the variable gain amplifier and the third frequency signal. A controller(108) controls the gain control rate of the variable gain amplifier and the phase control value of the variable phase shifter.
