Abstract: A system includes a first enclosure, a first input transmission line within the first enclosure, a first output transmission line within the first enclosure, and first one or more die within the first enclosure and laterally between the first input and first output transmission lines. The system further includes a second enclosure including conductive material, a second input transmission line within the second enclosure, a second output transmission line within the second enclosure, and second one or more die within the second enclosure and laterally between the second input and second output transmission lines. Dimensions of the first enclosure is substantially same as (e.g., within 2%) that of the second enclosure. A length of the first input transmission line differs from a length of the second input transmission line by at least 5%, the lengths being measured in a direction parallel to the lengths of the first and second enclosures.

Abstract: A switch matrix circuit module for routing signals. In an example, the module includes a switch matrix coupled with first and second switches. The switch matrix is configured to receive a plurality of input signals, and output a selected one of the plurality of input signals as a first intermediate signal and another selected one of the plurality of input signals as a second intermediate signal. The first switch receives the first intermediate signal and a first auxiliary signal, and outputs a first output signal, and the second switch receives the second intermediate signal and a second auxiliary signal, and outputs a second output signal. A number of the modules can be coupled together to provide a switch matrix circuit, which can be readily scaled by adding further modules. In an example, the plurality of input signals are radio frequency (RF) signals.
