摘要： The present invention relates to an apparatus and a method for compensating carrier feedthrough in a quadrature modulation system. In order to suppress the carrier feedthrough, and minimize and compensate the carrier feedthrough, differences of baseband differential input DC voltages in an in-phase as well as a quadrature-phase are simultaneously adjusted to 0 or a certain slight voltage difference by a simple analog circuit. Therefore, it is possible to suppress carrier feedthrough using a simple analog type apparatus for compensating carrier feedthrough, and simply achieve an apparatus for carrier feedthrough using a variety of quadrature modulators.

摘要： In a wideband mobile communication system, a signal transmitting apparatus separates an envelope curve signal which is size information and a phase signal which is phase information from a signal to transmit, and compares the envelope curve signal with a predetermined voltage. The signal transmitting apparatus performs active bias control that amplifies and outputs an envelope curve signal according to different driving voltages based on a comparison result, and supplies a bias voltage to a power amplifier that amplifies a phase signal based on the amplified signal.

摘要： The present invention relates to a scalable bandwidth system and a method of controlling a tunable filter. In the present invention, the scalable bandwidth system inputs, as a control signal of a tunable filter, a voltage corresponding to a section in which the capacitance according to an applied voltage is not practically changed for characteristics of varactor diodes, and inputs each control bit of the control signal to each varactor diode of the tunable filter to adjust the capacitance of each of the varactor diodes, and consequently adjusts the capacitance of the tunable filter by adding the capacitance of the varactor diodes.

摘要： Disclosed is an ink, which has a viscosity and a volumetric shrinkage, controlled to 20˜80 cP and 10˜30%, respectively, by controlling an amount of each of: (a) a first monomer having a viscosity of 7˜1,600 cP and having one or two polymerizable functional groups; and (b) a second monomer having a viscosity of 30˜20,000 cP and having at least three polymerizable functional groups, in the presence of 0˜20 wt % of a solvent, and which can form a convex portion due to its surface tension controlled to 20˜40 mN/m, so as to compensate for its volumetric shrinkage, wherein the viscosity and the surface tension are measured at 25° C. A substrate, which is patterned or information-recorded with the ink, and a display device having the substrate are also disclosed.
