Abstract: A chip to package interaction (CPI) test vehicle includes a chip including metal patterns contained in first and second sub-regions, respectively, and in which any one of the following comparable properties (a)˜(e) is the same among the first and second sub-regions, and another one of the properties (a)˜(e) is different among the first and second sub-regions: (a) size and shape of the sub-region, (b) metal density of the metal pattern, (c) type of the metal pattern, (d) distance between the sub-region and a center of the chip, (e) structure of the metal pattern.

Abstract: A repair fuse device is provided. The repair fuse device remarkably reduces the number of the enable fuse cuttings by making initial states of all repair fuse sets to a repair state, cutting an address fuse corresponding to a defective cell, and cutting an enable fuse corresponding to a defective redundancy cell.

Abstract: An array variable capacitor apparatus includes a line unit including a ground line and a signal line which operates as a lower electrode; and a plurality of plates which are engaged with the line unit to generate capacitance and which operate as upper electrodes, the plurality of plates being arranged in an array pattern and having different degrees of stiffness.

Abstract: A mobile platform apparatus for a multiple antenna system and an apparatus for verifying the mobile platform apparatus are provided.

Abstract: Provided is an apparatus for modulation in a base station with a smart antenna. The smart antenna system has many advantages that it is possible to deal with the large volume of subscribers; communication quality is increased; etc. However, the smart antenna system has disadvantages that cost is increased due to many antennas; base station transceivers have a complicated structure due to multiple antennas per base station; it is too complicated to manage resource and channel allocation; there is required compatibility with a conventional system; etc. The present invention provides an apparatus for modulation in a base station with a smart antenna, which can solve the foregoing problems by employing a modulator using a time division multiplexing method, a sector beam selector, and a TX beam former, thereby providing good compatibility regardless of a change in the number of base station sectors and the number of antennas.
