Description

Objective:This activity aims to design, develop and experimentally verify a low power planar ferrite switch including drive electronics.

Targeted Improvements:Footprint reduction of 40% in the RF section with respect to standard ferrite switches. Enabling highintegration of redundancy rings.

Description:There is pressure from payload primes and their customers to reduce the size and mass of payload hardware to allow a higher integration density. This is especially the case for geostationary multibeam systems, where a large number of components are needed, but also for small platforms, such as those intended for non-geostationary satellite constellations.

Redundancy is employed for active hardware e.g. LNA, SSPA, TWT, etc. Today redundancy is commonly implemented by a mechanical redundancy ring employing waveguide and coaxial switches, which are large and bulky and hence significantly contribute to the overall payload mass.

In this activity a planar ferrite switch shall be designed, developed, manufactured and experimentally verifiedfor redundancy applications. This includes the development of a redundancy ring concept. The selected implementation of the ferriteswitch shall allow the driver electronics to be placed close to and in the same package as the ferrite switch.

A possible approachcould be the use of low temperature co-fired ceramic (LTCC) technology, where the ferrite material is embedded in a suitable substrate. The integration of the control electronics together with the RF part shall be part of the activity.
