Abstract: PURPOSE: An acoustic transmission device of a frequency shift type and a method thereof are provided to remove a separate receiving device by using the nonlinear action of the human body. CONSTITUTION: A first modulator unit frequency-modulates a signal delivered from the sound source. The first modulator unit modulates the phase of the forged signal. A second modulator unit delays the signal delivered from the sound source. The second modulator unit modulates the frequency of the delayed signal. A ultrasonic transducer(160) changes each signal from the first modulator unit and the second modulator unit into the ultrasonic signal. The first modulator unit comprises a first RF modulator(120) and phase shifter(130). The second modulator unit comprises a time delay device(140) and a secondary frequency modulator(150).

Abstract: Provided is a mobile transmitter and a transmitting method thereof. The mobile transmitter includes a transmission circuit and a control circuit. The transmission circuit selectively operates as a polar transmitter or a direct-conversion transmitter. The control circuit controls an operation of the transmission circuit based on the level of an output signal. The mobile transmitter operates as a direct-conversion transmitter using a linear power amplifier with a high dynamic range when it transmits a low-power signal. Also, the mobile transmitter operates as a polar transmitter using a switching power amplifier with a high power efficiency when it transmits a medium-power or high-power signal. Thus, the mobile transmitter according to the present invention can provide both the high power efficiency (i.e., the advantage of the switching power amplifier) and the high dynamic range (i.e., the advantage of the linear power amplifier). Consequently, it possible to increase the battery lifetime of a personal portable communication terminal and also to implement to a compound terminal that can satisfy a variety of communication standards with a high dynamic range.

Abstract: 본 발명은 직접변환(direct conversion) 방식으로 고주파(RF) 신호를 베이스밴드(base-band) 신호로 하향변환(down conversion)시키는 주파수 혼합기(mixer)에 관한 것이다. 본 발명의 직접변환 주파수 혼합기는 단일 위상의 고주파(RF) 신호와 직교국부발진(quadrature LO) 신호를 이용하여 직교 베이스밴드 신호를 얻을 수 있는 구조로서, 제 1 주파수 혼합부는 0도와 180도 위상의 직교국부발진(LO) 신호를 이용하여 단일 위상의 고주파(RF) 신호를 인-페이즈(In-phase)의 베이스밴드로 직접하향변환(direct down conversion)시키고, 제 2 주파수 혼합부는 90도와 270도 위상의 직교국부발진(LO) 신호를 이용하여 단일 위상의 고주파(RF) 신호를 직교위상(quadrature-phase)의 베이스밴드로 직접하향변환시킨다. 직교국부발진(LO) 신호가 인가되는 트랜지스터와 고주파(RF) 신호가 입력되는 트랜지스터의 드레인과 소스가 각각 공통으로 연결되기 때문에 낮은 전원전압에서도 구동이 가능하다.
