RF switch matrix for a radiometer test chain

A second application of the RF matrix, for the test chain of an Earth-observation microwave radiometer. Delivered CE marked, with a web-server HMI.

Drawer open: radio-frequency plate with attenuators and power dividers, switching relay bank on the left-hand side
Internal view from the opposite side: power supply, forced ventilation and coaxial terminations on the rear panel

A variant of the RF switch matrix for the test chain of an Earth-observation microwave radiometer, for a European space prime contractor.

Two things differ from the first application: operation goes through an HMI served by an on-board web server, and the unit ships CE marked — that is, with technical file, risk analysis and declaration of conformity, which on a laboratory unit is not paperwork but the condition for admitting it to a manned integration hall.

The same switching architecture was carried across two different programmes. IN SY TO held component responsibility: design and AIT.
