Integrated receivers for mid-band SKA

Abstract

Abstract.A new System-on-Chip (SoC) receiver is proposed utilising an advanced Silicon on Sapphire CMOS process, to be developed as a collaborative venture between CSIRO Australia Telescope National Facility and an industrial partner. This receiver is targeted for mid-band SKA pathfinder use, covering an RF tuning range in excess of 700 to 1800 MHz, with a 300 MHz instantaneous bandwidth. The receiver features high dynamic range and low noise temperature. The Silicon on Sapphire process promises high reverse isolation and good device matching, allowing the use of a quadrature I/Q downconversion scheme. This paper summarises research to date on integrated receivers at CSIRO, as well as an overview of the proposed receiver design.
