摘要： A single stage unequal power combiner is proposed. Instead of conventional combiner plus impedance transformer of 2-stage unequal combiner, the single stage combiner gets rid of the input impedance transformer. The single stage combiner supports adjustable transmission line impedance and reasonable mismatch loss, assuming that the power ratio of the input signals is within a certain range. The single stage combiner also has an adjustable isolation resistor for different power ratios. A structure of switchable branch characteristic impedance, switchable isolation resistor for the unequal combiner is proposed as the preferred embodiment. In one advantageous aspect, broader coverage angle in a single array module can be realized via an antenna diversity switch.

摘要： The present disclosure relates to ultra-high speed digital signal integrity improving structures. Each structure in the present disclosure includes a first unit structure and a second unit structure of the same or different shapes arranged to face each other on the left and right sides along a longitudinal direction of a balanced line, centered around a coplanar stripline (CPS) or parallel stripline (PSL) formed on a substrate. At least one of the first unit structure and the second unit structure includes a first side close to the balanced line and having a linear or curve shape; a second side facing the first side; and left and right sides connecting the first side and the second side. Here, the width of the first side is less than or equal to that of the second side, the left and right sides have a linear or non-linear slope, and the width from the first side to the second side is configured to change continuously or discontinuously. When the structures of the present disclosure are disposed around a balanced line, it has the advantage of being able to recover the distorted phase autonomously while rejecting a common-mode signal in a frequency band up to 40 GHz or more.

摘要： A printed circuit board includes a first electrically conductive reference plane configured to distribute a first reference voltage applied thereto across a surface area of the first reference plane, and a second electrically conductive reference plane extending parallel to the first reference plane, and configured to distribute a second reference voltage applied thereto across a surface area of the second reference plane. A first layer is provided, which extends between the first reference plane and the second reference plane, and includes one or more first signal lines extending adjacent the first reference plane. The first layer is divided into: (i) a first region in which the one or more first signal lines are disposed, (ii) a second region containing an additional plane that is configured to receive a third voltage and has smaller surface area relative to the surface areas of the first and second reference planes, and (iii) a third region containing a dielectric layer. A second layer is provided, which extends between the first reference plane and the second reference plane, and includes one or more second signal lines extending adjacent the second reference plane. The second signal lines have linewidths that vary as a function of whether they are vertically aligned with the first region, the second region, or the third region.

摘要： This disclosure provides a feed network, an antenna apparatus, and a communication device. A main portion is disposed with a first electric-conductor and a second electric-conductor. In addition, two branch portions are disposed, one end of a first branch portion is electrically connected to the first electric-conductor, and one end of a second branch portion is electrically connected to the second electric-conductor. In this way, when two radiation parts in a same polarization direction of a radiating element are electrically connected to the first branch portion and the second branch portion respectively, a transmission structure of the feed network may feed two radio frequency signals, for example, two equi-amplitude phase-inverted radio frequency signals, into the two radiation parts of the radiating element respectively. The feed network in this embodiment of this application has a simple line, so that space occupied by the feed network in the antenna apparatus is reduced.

摘要： An on-chip dual-mode transmission line with an spoof surface plasmon based on a balun includes a dual-mode transmission line located in the intermediate, the balun structures symmetrically located at both terminals of the dual-mode transmission line, and pad structures and excitation portions located outside the balun structures. The dual-mode transmission line comprises two metal strip lines that are the same in structure and parallel to each other, and the branches located between the two metal strip lines. The dual-mode transmission line can simultaneously support the transmissions of the odd-mode spoof surface plasmon signal and the even-mode spoof surface plasmon signal, and is not only suitable for III-V chips such as gallium arsenide and silicon nitride, but also suitable for technologies such as other chips and printed circuit boards.
