Title:  "RF and microwave research in Manchester (UK) including SKA and a Ka band multi-beam array"

Abstract:

Danielle Kettle is a lecturer in the Electrical and Electronic
Engineering Department in The University of Manchester, UK. She
received her PhD from the University of Manchester. She has designed
and characterized several MMICs used in radio astronomy projects such
as the European funded FARADAY project and SKA prototypes. Her current
research interests include ultra low-noise HEMT characterization
(extraction of small-signal and noise models at both room and
cryogenic temperatures) and highly integrated low noise receiver
front-ends .  Danielle will give a talk on her work covering the
following areas:

	Microwave activities within the Microwave and Communication 
		Systems research group

	MMIC LNA designs: Ka Band, X Band 

	A Ka Band radiometer array with MMIC front ends

	SKA activities within the UK
