This activity involves development of frequency conversions from Ka-Band to intermediate frequencies at L and C-Band. In the same way, frequency conversions in the opposite direction is covered. The specific output of this development is four converter hybrid types. In addition the activity involves the design and development of three custom specific MMIC’s.
Hybrid models covered:
MMIC’s:
The main challenge in the program is related to build technology for Ka-band applications. Hence the risk mitigation associated with the use of hybrid technology at Ka-band is a major driver for the program.
In addition, the development of the MMIC’s includes an inherent risk, as the transistor models are not sufficiently mature for accurate simulations in the design phase.
To have an extended converter module library is regarded as necessity to be able to respond adequately to new commercial opportunities. Adequately in this context means responses with acceptable lead times, low cost and low risk.
The hybrid technology used in the program is well suited to both supporting the needed miniaturization for Ka-band as well as the mounting accuracy needed for repeatability and predicted performance
Based on the Kongsberg Space Electronics modular build and
implementation technology variants of these hybrids can be developed meeting also other specific band and bandwidth variants.
Through critical breadboard demonstration and characterization an important fundament is established for further implementation in new hardware.
The frequency converter hybrids can be used in many different architectures as frequency translation is mandatory for almost all kinds of satellite communication equipment. This could be frequency conversions at the input or output of digital processors in beamforming systems, or frequency conversion in ISL (Inter Satellite Link) systems.
