T102-10ET
GaN Highly Efficient HPA for X- and Ku-band SAR and Altimeter Applications
Semiconductor components based on GaN material have already demonstrated unparalleled performances on laboratory
level compared to classical GaAs based materials. The prospects are impressively good. The material properties are ideal for
radar applications. Power levels can be achieved, which were in former times the domain of vacuum devices like travelling
wave tubes.
Within the framework of this activity an HPA device shall be designed, manufactured and tested for demonstration of high
power handling capability at X and Ku-band.

Title:
GaN Self Protected LNA for X- and ku-band Radar Applications
Semiconductor Components based on GaN material have already demonstrated unparalleled performances on laboratory
level compared to classical GaAs based materials. The prospects are impressively good. The material properties are ideal for
radar applications. GaN is very often only proposed for high power applications, although the material has excellent noise
properties very close to GaAs based materials. The high breakdown voltage is of great importance because this allows save
operation in the vicinity of high power levels, typical for all Radar applications. Limiter always needed in conjunction with GaAs
devices will become unnecessary or only very simple device. Noise figure is going to improve. Furthermore if considered for
integration in T/R Modules The power device and the LNA can be integrated on the same chip. Two chip or even single chip
T/R modules become feasible with corresponding cost advantages.
Deliverables:
Tested demonstrator LNAs with and without on chip limiter in X and Ku band. Design and Test Documentation.

Title:
Innovative Low-loss FSS structures
The objective of this activity is to develop an accurate computer model to design multi-layer mesh filters. The simulation tool
will account for the effects of non-perfect element shapes, metal conductivity and slot thickness. Investigate potentially
suitable novel materials and micromachining techniques and create controllable and repeatable fabrication routes with suitable
structural properties. Investigate potentially suitable techniques to make all-metal FSS structures and create controllable and
repeatable fabrication routes with suitable structural properties. This should be followed by preliminary fabrication trials and
process optimization. Measurements will be performed to quantify the efficiency improvement and increased out of band
rejection. If applicable, existing prediction tools will be updated to explain discrepancies with theory and experiment.
Deliverables:
FSS hardware, prediction tools, full performance report.
