A remote radio head unit (RRU) system for multiple operating frequency bands, multi-channels, driven by a single or more wide band power amplifiers. More specifically, the present invention enables multiple-bands RRU to use fewer power amplifiers in order to reduce size and cost of the multi-band RRU. The present invention is based on the method of using duplexers and/or interference cancellation system technique to increase the isolation between the transmitter signal and receiver signal of the RRU.

A processing method for ceramic, having processing steps consisting of: (a) Manufacture pellets; (b) Cover the pellets with microwave dielectric; (c) Place the pellets into a microwave environment; (d) Microwave degreasing; (e) Complete degreasing. Procedural steps of the present invention primarily consist of placing the ceramic pellets in a container filled with microwave dielectric powder, placing the container within the microwave environment, and then regulating microwave power and time period for degreasing, whereupon the microwave dielectric powder surrounding and covering the pellets subsequently absorbs the microwaves and thereby facilitates indirect degreasing of the pellets.

The present invention relates to an optically integrated device, and more particularly, to an optically integrated device with low light loss. A color filter is attached to an optical integrator to filter through a portion of the light, and reflect the other portion of the light back to the optical integrator. The optically integrated device recycles the reflected light inside the optical integrator to prevent light loss.

A substrate for securing a photoelectric device chip is provided. The substrate includes a metal base and a dielectric layer. The metal base includes a die bonding region and a peripheral region surrounding the die bonding region, and the die bonding region is for securing the photoelectric device chip. The dielectric layer is disposed on the metal base and located in the peripheral region to define the die bonding region; the metal base is formed with at least one groove corresponding to the die bonding region, and the at least one groove is filled with a thermally conductive filler; and a filling density of the thermally conductive filler in unit of volume of the metal base is gradually reduced along a direction from a center to an edge of the die bonding region. Heat conducting efficiencies of various regions of the substrate are controllable and adjustable.

The present application provides a liquid crystal material, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel. The liquid crystal material of the present application includes liquid crystal molecules, polymerizable monomers and a reactive vertical alignment material, the polymerizable monomers and the reactive vertical alignment material can occur a polymerization under ultraviolet irradiation to form a polymer, while the polymer deposits on a substrate to form a polymer film capable of replacing the PI alignment film, the reactive vertical alignment material includes a polymerizable group L that strengthens polymerization ability of the reactive vertical alignment material, increases compactness of forming the polymer film, improves morphology of the polymer film, and enhances panel quality. The method of fabricating the liquid crystal display panel of the present application eliminates the fabricating process of the PI alignment film, the method has simple process and low cost. The liquid crystal display panel utilizes the polymer film, which is obtained by polymerizing the polymerizable monomers and the reactive vertical alignment material, to replace the PI alignment film, so as to greatly enhance quality of the panel, and to have a low fabricating cost.

A manufacturing process of an emboss type flexible or rigid printed circuit board includes multiple steps. First, a layer of dry film is applied to a layer of copper foil. Then a circuit pattern is formed on the copper foil through photolithography processes. An etching stop layer is electroplated on the circuit pattern. The etching stop layer is then electroplated with copper. The copper foil is softened by a high temperature process after removing the dry film. Then the layer of the copper foil is etched after coating with an organic surface layer and the organic surface layer is solidified.
