摘要： A surface mountable transformer integratable into a printed circuit board. In one aspect, the transformer comprises two broadside vertically coupled transmission lines. In another aspect, the transformer may comprise two broadside vertically partially coupled transmission lines. The layout of the transformer is adaptable for use in microwave modules where transformers are integrated into the printed circuit board and the active components are mounted in the cavity. The layout preferably requires only two signal areas. In addition, an aspect of the present invention allows the differential or unbalanced ports to lie on the same surface as the balanced port.
摘要翻译：可表面安装的变压器可集成到印刷电路板中。在一个方面，变压器包括两个宽边垂直耦合传输线。在另一方面，变压器可以包括两个宽边垂直部分耦合的传输线。变压器的布局适用于微波模块，其中变压器集成到印刷电路板中，有源部件安装在空腔中。布局优选仅需要两个信号区域。此外，本发明的一个方面允许差分端口或不平衡端口位于与平衡端口相同的表面上。

摘要： The present invention relates to a single side band modulator for splitting a signal into a first split signal and a second split signal 90 degrees out of phase with the first split signal. A first double balanced mixer modulates the first split signal and includes a transformer, a modulating signal input, and a first diode ring. The transformer connects the first diode ring to a quadrature hybrid. A second double balanced mixer modulates the second split signal and includes a transformer, a modulating signal input, and a second diode ring. The transformer of the second double balanced mixer connects the second diode ring to the quadrature hybrid. The first and second diode rings are connected in parallel and are connected to a third transformer which performs the function of a power combiner.
