Lucyszyn S, Sewell T, Robertson ID, 2007, Multi-level digital modulation performed directly at carrier frequency, 25th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 673-676
Direct modulation of the carrier signal has been shown to be an attractive means of reducing the complexity of the RF hardware required in a communications transceiver. To this end, a proof-of concept X-band vector modulator, realised using monolithic phase shifters and attenuators, has been used to demonstrate that multi-level digital modulation can be implemented at high data rates and without requiring significant control power. The measured constellations for QPSK, 32-PSK and 16 QAM modulation are presented. This technique is suitable for both microwave and millimetre wave appicatons.
Lucyszyn S, Robertson ID, 2007, High performance analogue MMIC control devices for adaptive phased array applications, 24th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 1796-1801
Three different MMIC analogue reflection-type control devices are presented. The variable delay line is the first to be realised using monolithic technology, while the phase shifter and attenuator have been designed to achieve optimal bandwidths. With all of the devices, high levels of performance were measured across the 8-12 GHz frequency range.
Lucyszyn S, Pilchen Y, Robertson ID, et al., 2007, Ku-band serrodyne frequency translator using wideband MMIC analogue phase shifters, 23rd European Microwave Conference Proceedings, Publisher: IEEE, Pages: 819-822
A novel Ku-band serrodyne frequency translator is presented which employs wideband MMIC analogue phase shifters. The MMICs have a simple topology and are fabricated using low cost foundry processing techniques. The resulting highly nonlinear tuning behaviour of the complete 360° phase shifter is overcome with two different types of modulating signal: the first having a predistorted sawtooth function (using DSP techniques) and the second having a linear sawtooth function (resulting in 20% under-modulation). With an input carrier frequency of 14GHz, the measured results demonstrate high levels of carrier suppression and unwanted sideband suppression, with both functions. This performance was maintained at all carrier frequencies in the 13 to 15GHz frequency range - without having to modify the functions. In addition, 0dB conversion loss was achieved and almost no control power was required.
Lucyszyn S, Robertson ID, 2007, An improved multi-layer quadrature coupler for MMICs, 21st European Microwave Conference Proceedings, Publisher: IEEE, Pages: 1154-1158
Abstract:A novel technique for significantly reducing the insertion loss of multi-layer quadrature couplers is presented. With previous broadside multi-layer couplers, realized on GaAs MMICs, the upper conducting layer track is overlayed exactly onto the much thinner lower conducting layer track - resulting in a high insertion loss. A new multi-layer structure is presented that has an upper track which is offset - so that the lower track can be plated-up with the much thicker metal from the upper track, thus, reducing the even-mode insertion loss. A coupler, with a centre frequency of 7.7GHz, incorporating this technique has been realized on a GaAs MMIC, with maximum dimensions of only 1.l×0.8mm. The resulting insertion loss at centre frequency is less than 1dB. The overall performance has been found to equally match that of the Lange coupler.
Lucyszyn S, Oztek-Yerli CF, Robertson ID, 2007, Accurate modelling of cold-MESFETs for adaptive MMIC signal processing applications, 25th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 1177-1180
At microwave frequencies, variable resistors can beimplemented with cold-MESFETs. An accurate ultrawidebandmodel for cold-MESFETs is presented. Theequivalent circuit model is based on the physicalstructure of the device and has a simple topology thatrequires only two bias dependant elements. The modelhas been used to accurately characterise coldMESFETsfrom 0.05 to 20.05 GHz. Moreover, unlikethat for a switched-MESFET, the model is accurate overa continuous and wide range of bias points.
McPherson DS, Stubbs MG, Wight JS, et al., 2007, A 28 GHz HBT vector modulator and its application to an LMCS feedforward power amplifier, 28th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 523-528
A vector modulator employing four amplitude modulated orthogonal channels is presented. Operating at 28 GHz, this device consists of a four-way 6 dB power divider, four GaAs HBT MMIC variable gain amplifiers, and a 4-to-1 power combiner All of the passive functions were realised on alumina ceramic while the amplifier chips were fabricated at Nortel Technologies using a 3.5 μm × 6 μm GaInP-GaAs HBT process. By testing a vector modulator prototype, we were able to evaluate the architecture and be the first to assess its suitability as a gain/phase control element for a Ka-band MCS adaptive feedforward lineariser.
Chrisostomidis CE, Guglielmi M, Young PR, et al., 2007, Application of chained functions to low-cost microwave band-pass filters using standard PCB etching techniques, 30th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 40-43
In this paper, the application of the chained function polynomials to the design of low-cost microwave band-pass filters is presented. The chained function concept provides a variety of transfer functions to choose from, each one having different characteristics and different implementation requirements. Thus, reduced sensitivity to manufacturing tolerances can be achieved by selecting the appropriate transfer function for a given manufacturing technology. The achieved reduction is confirmed experimentaly at millimetre-wave frequencies, using parallel-coupled line band-pass filter designs manufactured using standard PCB etching techniques.
Lucyszyn S, Robertson ID, Aghvami AH, 2007, Monolithic analogue phase shifter and cascode FET amplifier using uniplanar techniques, 24th European Microwave Conference Proceedings, Publisher: IEEE, Pages: 554-559
A precision millimetre-wave analogue phase shifter and a miniature Ku-band cascode FET amplifier are presented. Both MMICs are realised using uniplanar technology. The phase shifter employs a blend of coplanar waveguide and multilayer techniques. It has a worst-case rms phase error of only ± 1.0°, for all levels of relative phase shift up to 120°, across the 31 to 32 GHz frequency range. The amplifier is realised using a combination of coplanar waveguide, meandered 'thin-film' microstrip, and lumped elements. The amplifier has an active area of only 0.9 mm2 and a measured gain of over 12 dB at 15 GHz.
