Description

{RF TERMINAL DEVICE}

The present invention relates to an RF terminal apparatus, and more particularly, to a connection structure in an RF terminal apparatus.

2. Description of the Related Art Generally, an RF (Radio Frequency) terminal device such as a mobile communication terminal is composed largely of an external case frame and a printed circuit board provided in the case frame. The printed circuit board is constituted by a plurality of integrated circuits and various chips, and converts the generated voice or data into signals suitable for transmission and reception, and transmits the converted signals through the antenna unit.

Such an RF terminal apparatus is manufactured and assembled and then released after verifying its characteristics through a predetermined evaluation method. In general, the measurement of the characteristics of the RF terminal apparatus measures the degree of transmission / reception of radio waves and the operating characteristics , It is measured under the same conditions as those actually used by using external test equipment.

To this end, a printed circuit board of an RF terminal device is mounted with a mechanical switch, usually referred to as an RF switch. The RF switch may be connected between an antenna and a signal processing unit such as a duplexer to control an RF signal path.

That is, the RF switch normally switches the RF signal path between the signal processing units in the antenna so that an RF signal path is formed between the signal processing unit and the test equipment when the connection pin of the test equipment is connected.

Referring to the patent document (Japanese Unexamined Patent Application Publication No. 10-2010-0077658), in order to insert and fix the connection pin of the test equipment and structurally perform the switching operation according to the insertion of the connection pin, It can be seen that the complex structure is installed in the structure. Accordingly, the conventional RF switch has a large size and a high structure.

The RF switch having such a structure becomes a factor of raising the unit price of the RF terminal apparatus, and is a constraint factor for the slimness and the miniaturization trend of the recently required products.

On the other hand, there is a problem that transmission / reception performance (hereinafter, radiation performance) is lowered when a metallic object exists in the vicinity of the antenna of the RF terminal apparatus. Generally, the RF switch is positioned near the antenna, Ensure separation from the antenna so that performance is not affected. However, there is a difficulty in securing the separation distance in the recently miniaturized and slimmed RF terminal device.

Therefore, there is a growing need for an RF terminal apparatus and a method and system for measuring the characteristics thereof, which can solve the above-mentioned problems.
