Abstract: A multi-layer radio frequency chip balun comprises a multi-layer dielectric structure. The equivalent circuit of the multi-layer dielectric structure comprises mainly an input port, first and second output ports, and a few even sections of broadside coupled lines. Each section of the coupled line is wired in a particular shape and is composed of two coupled lines. Each section of coupled line corresponds to a coupled coefficient. The sections of the coupled lines have completely symmetric structures on two sides with respect to the center geometrically. Both phase and amplitude are well balanced at the balanced ports. Moreover, the balance of phase and power can be adjusted by inserting a transmission line between two broadside coupled lines to achieve more complicated impedance match. The balun can be fabricated with low dielectric constant materials. In addition to the reduction in cost, the stability of the balun is also improved.

Abstract: The present invention provides a method for forming high purity gold foil. The method primarily includes the steps described as follows. Gold bullion is positioned in a vacuum environment and then vaporized using electrical process and thus becomes powder. Next, the gold powder suspended above the gold bullion is attracted and temporarily accumulated on the surface of the substrate due to the static electricity applied on the substrate. The particles of the gold powder gather and become the high purity gold foil.
