Title:
T102-28ET
Development Schottky MMICs for high frequencies
Schottky diodes are generic components that are used in practically all millimetre and sub-millimetre wave receivers. They are
especially critical to future Earth observation instruments. Since the availability of Schottky technology for frequencies above
100 GHz is very limited (single U.S. supplier), it is important to develop a European source.
United Monolithic Semiconductors (UMS) is a European GaAs foundry that has a dedicated Schottky MMIC process
commercially available for applications below 100 GHz. Preliminary studies have indicated that it is possible to introduce
modifications that will improve the performance at higher frequencies, without changing the core fabrication process.
The aim of this activity is to investigate theoretically and experimentally such modifications, develop the device design and the
necessary processing steps, and demonstrate the improved performance at 200/300 GHz.
The activity will include a theoretical study for diode optimisation using device and EM simulators, design of the discrete
devices and MMIC Demonstrators, fabrication run(s) using the BES process of UMS, process experiments for different
modifications in the fabrication, and the design, construction and characterisation of the Demonstrators. The Demonstrators
will consist of discrete devices and fully functioning MMICs (mixer/multiplier) for 200/300 GHz. At least one MMIC will be
mounted and characterised in a waveguide housing.
Deliverables:
Characterised Demonstrators (discrete devices and MMICs). Definition of processing modifications.

Title: Active Receive-Only Digital Front-End for Radar and SAR - Phase 1 & 2
Traditional SAR design has a well-known limitation between resolution and swath width, which have to be traded-off. A way
out of this limitation is in the introduction of a bi-static approach with separated transmit and receive antenna, mounted on the
same platform. This leads to the novel high-resolution wide swath approach for SAR, which makes use of innovative digital
beam forming during receive and solves in this way the well known restriction.
- Within phase 1 of the proposed activity a SAR system design based on this new concept shall be carried out. The key
system performance parameters have to be determined by simulation and evaluated in comparison to traditional approaches.
Critical components and subunits needed for a front-end demonstrator have to be identified and specified.
- In phase 2 of the activity the critical components and subunits have to be breadboarded and feasibility shall be
demonstrated. The scan while receive function, the key feature, has to be demonstrated.
Deliverables:
Fully tested Digital Rx-only Tile Demonstrator. Documentation.
