  • Publication number: 20240080002
    Abstract: A low-noise amplifier in a receiver supporting a beam forming function may selectively change a phase shift for beam steering. The low-noise amplifier may include first and second transistors and a variable capacitance circuit connected to a gate of the second transistor. The variable capacitance circuit may selectively change capacitance thereof based on a capacitance control signal applied thereto according to beam-forming information, where the changed capacitance correspondingly causes a phase change in an output signal of the low-noise amplifier. A similar scheme may be employed for amplifiers in transmit signal paths to steer a transmit beam.

  • Patent number: 6908975
    Abstract: The present invention relates to a method for preparing a high 1,4-cis polybutadiene having a controlled cold flow and, more particularly, to a novel method for preparing a high 1,4-cis polybutadiene having a controlled cold flow that involves initiating polymerization of a 1,3-butadiene in the presence of a non-polar solvent using, as a polymerization catalyst, a complex prepared by mixing a neodymium compound with or without a conjugated diene compound, a halogenated organoaluminum compound or a halogenated organic compound, and an organoaluminum compound irrespective of the addition order of the catalyst; and adding an organoborane compound as a cold flow controller of 1,4-cis polybutadiene after a predetermined time of the polymerization. Accordingly, a high 1,4-cis polybutadiene having an efficiently controlled cold flow can be prepared without causing a significant increase in the Mooney viscosity (molecular weight), an odor (bad smell), and a reduction in 1,4-cis content and polymerization yield.
