Introduction: The recent development of millimetre-wave CMOS and SiGe circuits have made silicon technologies attractive also for noncommercial low-volume applications such as the atmospheric remote sensing where III–V compound semiconductors have been traditionally used for the millimetre-wave receiver technology. The possibility to integrate more functions on the same silicon chip would enabl...

An integrated optical millimetre-wave signal generator based on a coupled microring resonator, which doubles the frequency of the electrical signal driving a phase modulator, is proposed and experimentally demonstrated for future radio-over-fibre systems. The coupled microring notch filter was fabricated on a silicon-on-insulator wafer. A high extinction ratio optical millimetre-wave signal was...

This paper describes a technique used to measure oscillator noise sidebands at 94GHz. It is extendible to other frequencies in the millimetre-wave band. Oscillator noise sidebands are particularly significant for Continuous Wave (CW) radars, where the sidebands of the transmit/receive leakage can degrade the system noise figure. Measuring oscillator noise is also a particular challenge at highe...

Sensing infrared radiation is done inexpensively with pyroelectric detectors that generate a temporary voltage when they are heated by the incident infrared radiation. Unfortunately the performance of these detectors deteriorates for longer wavelengths, leaving the detection of, for instance, millimetre-wave radiation to expensive approaches. We propose here a simple and effective method to enh...

The MiWaveS (Beyond 2020 heterogeneous wireless network with Millimetre Wave Small cell access and backhauling) project aims to contribute some key aspects to the ongoing definition of 5G, i.e. the next generation of wireless telecommunications [2]. Specifically, it will show how high-throughput and low-latency heterogeneous mobile networks, based on flexible spectrum usage of the millimetre wa...

The HARP (Heterodyne Array Receiver Programme) B-band camera will incorporate a focal-plane array of 16, 850 micron (325-375 GHz), SIS heterodyne detectors. This receiver has been commissioned for use on the James Clerk Maxwell Telescope in Hawaii. The complete instrument will o er greatly improved spectroscopic mapping speeds (>x10) of extended objects complementing existing continuum bolomete...

Investigations on the biological impact of low levels of millimetrewave energy date back to the first experiments on the generation and detection of these high-frequency signals by Sir Jagadis Chunder Bose at the end of the 19th century. Slightly more than a hundred years later, millimetre-wave transmission has become a ubiquitous commercial reality. Despite the widespread use of millimetre-wav...

CSIRO ICT Centre is developing millimetre wave point-to-point links suitable for multigigabit wireless connectivity. Suitable spectrum for this purpose is allocated at the 60 GHz band and above. This paper reports a new point-to-point link that will be installed at Marsfield site to demonstrate multi-gigabit operation and performance of its key components. The link will operate at the 81-86 GHz...
