Embodiment Construction

[0057] Embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0058] figure 1 An example of a Wilkinson combiner / splitter 10 is shown schematically. The combiner / splitter 10 has a first port 2 , a second port 14 and a third port 16 . When operating as a splitter, the first port 2 can be used as an input port and the ports 14, 16 can be used as output ports. Conversely, when operating as a combiner, the first port 2 can be used as an output port and the ports 14, 16 can be used as input ports. The combiner / splitter 10 has two λ / 4 lines 4, 6 whose characteristic impedance is sqrt(2)*Z 0 The value between and 2*Z 0 Resistor coupling for isolation purposes. For example, when the combiner / splitter 10 is used as a splitter, the signal input at port 2 is split into two equivalent paths along lines 4, 6 with an insertion loss of about -3dB.

[0059] although figure 1 The Wilkinson combiner / splitter 10 is shown with two ports 14,...

Abstract

A power combiner / splitter for multiple input multiple output (MIMO) applications and a method of making the same. A metallization stack has a plurality of layers including patterned metal features forming first and second branched arrangements of the power combiner / splitter. Each branched arrangement includes a port located at one end of that branched arrangement, and a plurality of further ports. Each branched arrangement also includes a plurality of bifurcated branches extending between each end of that branched arrangement for dividing / combining a signal passing through that branched arrangement between the port and the plurality of further ports. The metallization stack further includes a common ground plane that is shared by the first and second branched arrangements. At least some of the patterned metal features forming the first branched arrangement overlie at least some of the patterned metal features forming the second branched arrangement.

Description

Background technique [0001] This specification relates to a type of power combiner / splitter that can be used in millimeter-wave (mm-wave) applications requiring multiple-input multiple-output (MIMO) operation. [0002] The Wilkinson combiner / splitter is a popular device for mm-wave designs. Although a Wilkinson combiner / separator implementation may be relatively simple in general, it may typically occupy a lot of real estate on the substrate. Nonetheless, as the demand for mm-wave integrated circuits (ICs) increases, this type of device can be integrated on silicon and / or laminate-type structures. [0003] For analog beamforming (phased array operation), it is highly desirable to provide a dual polarized patch antenna that allows MIMO operation. Therefore, the two Wilkinson synthesizers must be integrated. Contents of the invention [0004] Aspects of the present disclosure are set out in the accompanying independent and dependent claims. Combinations of features from th...
