    摘要： Provided is an optical hybrid module in which an optical device, a filter, an amplifier and an antenna are hybrid-integrated, which includes: a silicon optical bench disposed on a substrate and having an optical fiber and an optical device; an amplifier disposed on the substrate and connected to the optical device disposed on the silicon optical bench to amplify a signal transmitted from the optical device; and an antenna disposed on the substrate to be connected to the amplifier and transmitting a signal amplified by the amplifier. Thus, a foot-print module may be embodied by disposing an antenna and a filter on a single- or multi-layer substrate and providing a bias required for the optical device and the amplifier through a solder ball. Also, due to the antenna and filter disposed on the substrate, an expensive connector is not needed, and thus a production costs can be reduced.

    摘要： Provided are a wafer level package in which a communication line can be readily formed between an internal device and the outside of the package, and a method of fabricating the wafer level package. The wafer level package includes a first substrate having a cavity in which a first internal device is disposed, an Input/Output (I/O) pad formed on the first substrate and electrically connected with the first internal device, a second substrate disposed over the first substrate and from which a part corresponding to the I/O pad is removed, and a solder bonding the first and second substrates. According to the wafer level package and the method of fabricating the same, upper and lower substrates are sawed to different cutting widths, or a hole is formed in the upper substrate, such that a communication line of an internal device can be readily formed without a via process which penetrates a substrate. Therefore, in comparison with a conventional wafer level package fabricated using the via process, it is possible to simplify a fabrication process and reduce production cost.

    摘要： In a digital receiver, a noise attenuation and signal magnitude mapping variable amplifying unit includes a filter and an amplifier, amplifies and band-bass filters an analog signal and attenuating white noise and an interference signal other than a band signal. An ADC performs subsampling on a carrier frequency of a desired signal and performs oversampling on the band of the desired signal by using a sampling frequency to convert the analog signal which has passed through the noise attenuation and signal magnitude mapping variable amplifying unit into a digital signal of a direct conversion frequency band or an intermediate frequency band. The ADC has a dynamic range for processing both the desired signal and an undesired signal adjacent to the desired signal. A digital signal processing unit converts a signal frequency of the digital signal or digital-filters an undesired signal within the digital signal and processes the digital signal by digitally adjusting a gain.
