SKA High Speed Probe
High-speed probe

The Square Kilometre Array (SKA) is a revolutionary all-electronic telescope for the 21st century and is being planned as a next-generation 'discovery' telescope with a collecting area of a square kilometre.

This will be a distributed array with up to 100 times the sensitivity of the most powerful radio interferometers currently available and enabling survey speeds that are 100 times faster.

Development of technology and key components for the SKA project is currently being undertaken within the UK with funding from both the Science and Technology Facilities Council and EC Framework 6, in a project called the Square Kilometre Array Design Study (SKADS).

The collaboration between Manchester and Selex in the SKA context addresses key technology and components for the low-band phased array elements of SKA, including the development of innovative, dedicated front-end semiconductors and MIMIC components utilising novel InP-based HEMT and HBT technologies for Low-Noise Amplification and Analogue to Digital Conversion.

The collaboration has been recently extended to include the further development of this InP-based technology for a wider range of applications across the commercial, civil and defence fields.

This development is aimed at achieving a very high frequency range for digital and analogue operations of the circuits, with both Ft and Fmax > 200 GHz, and includes combining the HEMT and HBT devices into a single BiFET process. Initial funding for this has been provided by the Electromagnetic Remote Sensing Defence Technology Centre.
