April 11, 2022, 1:46 a.m. Updated 35 {"title": ["", "Development of a High Frequency Phase Reference Standard"], "description": ["", "\nRecent advances in microwave test equipment through the use of microwave sources\nemploying Direct Digital Synthesis (DDS) techniques enable frequencies up to 67GHz to be\nachieved. When these are combined with state-of-the-art Vector Network Analyser (VNA)\nreceivers, new opportunities are opened up to develop current and voltage waveform\nmeasurement systems, including active load-pull systems, that operate at very high\nfrequencies. The major technical hurdle that prevents this from being possible is the provision\nof an accurate, wide-band phase reference which is required to convert a frequency domain\nVNA into a time domain receiver capable of handling current and voltage waveforms.\nAttempts have been made to solve this issue through the development of new types of phase\nreference standards, however all of the approaches tried to date have been severely limited in\ntheir frequency of operation. This research project would therefore look into the feasibility of\ndeveloping a new type of phase reference that is not frequency limited, but could in principle\nbe used to frequencies up to 67GHz and beyond.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
