SWITCHABLE AND TUNABLE MOBILE ANTENNA CHIP FOR ADVANCED LTE ANTENNA

摘要

A switchable and tunable mobile antenna chip is disclosed. The switchable and tunable mobile antenna chip of the present invention is a mobile antenna chip connected to an antenna which transmits and receives a signal. A switchable solution of single-pole-n-throw (SPnT) or double-pole-n-throw (DPnT) type which selects a plurality of frequency bands by being connected to the antenna and transmits and receives it, and a tunable solution connected to the antenna in a switchable solution chip are formed in a single antenna chip. The antenna chip compares a signal which is received and transmitted by the antenna in real time with a radiation level or a reception level of a standard antenna and is connected to a main chip and a controller which transmit a control signal to the antenna chip of the switchable solution and the tunable solution to compensate the difference. According the present invention, a single chip capable of having the frequency moving property of the switchable solution and the antenna matching property of the tunable solution can be manufactured.
