Radio frequency signal digitisation and data transport
This project focuses on the design and development of a cost-effective integrated 0.5-2GHz radio receiver for the square kilometre array (SKA) telescope based on Complementary Metal Oxide Semiconductor (CMOS) technology. The SKA will have thousands of phased array antenna dishes required for the mid-band receivers, where each dish will have up to around 200 receiver elements.
Around a million individual receivers will be required to detect, digitise and optically-transport the broadband radio data to remote signal processors. Because of the multiplication effect, there is a need to have a high-speed, power efficient and cost-effective solution to address these challenges. Furthermore, the radio frequency signal digitisation and data transport solution should be able to be upgraded easily without changing much of the receiver architecture (as the semiconductor technology advances), to cover and possibly extend the lifetime of the SKA receiver beyond the year 2050.
The ultimate aim of this project, is to design and develop am integrated broadband and low-power analog-to-digital converter (ADC) in conjunction with multiplexers and laser drivers to realise an integrated radio receiver prototype for SKA signal digitisation and optical transport, covering a frequency range 500MHz to 2GHz.
