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.

The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts.

A manufacturing process of an embedded 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 copper foil according to 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 layer and the organic layer is solidified.
