MOBILE COMMUNICATION TERMINAL CAPABLE OF REDUCING CALIBRATION ERRORS CAUSED BY A SWITCHING ERROR

摘要

PURPOSE: A mobile communication terminal is provided to reduce manufacturing costs by using an RF(Radio Frequency) connector without a switching function which is cheaper than an RF switch connector with the switching function.;CONSTITUTION: A connection unit is connected between a switching unit(210) and an amplifying unit(220). The connection unit connects the switching unit with the amplifying unit. The connection unit includes a terminal connected to a cable of a measuring instrument. A transceiving unit(200) includes a first and a second chip antenna. The amplifying unit includes a first set and a second set of LNAs(Low Noise Amplifiers). The switching unit includes a first set and a second set of SPDTs(Single Pole Double Throws).;COPYRIGHT KIPO 2013
