    摘要： A dust collection assembly of a vacuum cleaner is provided. The dust collection assembly includes a dust collecting box, a filter, a flow guide unit, an exhaust guider, and an upper cover. The dust collecting box and the flow guide unit are integrally formed in a single body. The dust collecting box includes a first and second dust collecting spaces for collecting foreign objects. The filter is disposed in the inside of the dust collecting space to primarily filter foreign objects during operation of a cyclone. The flow guide unit guides airflow and has small cyclones integrally formed therein, for secondarily filtering the foreign objects in air. The exhaust guider guides airflow and has a plurality of discharge holes through which air filtered by the small cyclone flows. The upper cover is disposed on the upper side of the exhaust guider.

    摘要： Provided is a power amplifier of a low-power consumption system that has linearity at a peak output power while increasing efficiency in a most frequently used range, and thereby enables a battery to last longer. The power amplifier includes an input impedance matcher for impedance-matching a signal input from the outside; a high-power amplifier and a low-power amplifier for amplifying the signal having passed through the input impedance matcher; an amplification controller controlling the high-power amplifier and low-power amplifier according to the power level of the input signal; an output impedance matcher for impedance-matching the signal amplified by the high-power amplifier and low-power amplifier; and a dynamic voltage supplier for supplying the low-power amplifier with a variable driving voltage. With the constitution set forth above, linearity at peak output power is maintained, and efficiency increases in the most frequently used range, thereby enabling the battery of a handheld to last longer.
