    Abstract: Provided is an amplifier structure. The amplifier structure includes a delta-sigma modulator, an up converter, a power amplifier, and a band-pass filter. The delta-sigma modulator receives an IF signal to delta-sigma modulate the IF signal. The up converter up-converts a frequency of the delta-sigma modulated signal with an LO signal. The power amplifier amplifies a power of the up-converted signal. The band-pass filter filters the amplified signal of a selected band. The amplifier structure performs the delta-sigma modulation operation on an IF input signal, and thus can considerably decrease a delta-sigma modulation operation speed compared to a typical amplifier structure and moderate the specification in implementing a power amplifier.

    Abstract: Disclosed herein is a printed circuit board, including: a substrate including a first circuit layer formed on one side thereof and a second circuit layer formed on the other side thereof; and a strike-type through body externally inserted in the substrate and electrically connecting the first circuit layer and the second circuit layer. The printed circuit board is advantageous in that, since a strike-type through body is externally inserted in a substrate, conventional complicated processes, such as hole forming, deburring, desmearing, electroless copper plating and electrolytic copper plating, can be omitted, thus simplifying a process of manufacturing a printed circuit board and reducing the manufacturing cost thereof.
