This paper intends to answer the question how to achieve wireless data rates that can catch up with current Internet speed, from a basic physics point of view. It is shown that the traditional electric circuit theory and design methodology that have been used for generations are unfortunately not adequate for wireless communications in the future. Instead, disruptive approaches, such as six-port modulators for processing of electromagnetic waves and optical pulses, should be employed to push up the wireless data rate above 100 Gb/s. The key variables to consider for high-speed digital communications are bandwidth, modulation order, and signal-to-noise ratio. In principle, it should be possible to achieve a wireless data rate at 100 Gb/s within the frequency spectrum below 20 GHz.INDEX TERMS Circuits and systems, communication technology, direct optical-to-wireless data conversion, full wave approach, high modulation order, internet speed, parallel processing, six-port modulator, wireless communication, wireless data rate.

“…The idea of using a multi-port circuit in direct conversion microwave receivers for radars [33] or wireless communications [34,35] was proposed for the first time at the Poly-Grames Research Centre of "École Polytechnique de Montreal" between 1994 to 1996. The first reported results were related to the narrow-band single-carrier demodulation of digital data.…”

Recent advances in millimeter wave technologies, both in component and system design, in line with important size and cost reductions, have opened up new applications in ultra-high-speed wireless communications, radar and imaging sensors. The paper presents the evolution of millimeter wave circuit and modules fabrication and characterization technologies in the past decades. Novel planar low-cost fabrication technologies have been successfully developed in this period. In combination with the standard rectangular wave-guide technology, these offer great opportunities for prototyping and testing of future millimeter wave transceivers or front-ends, which integrate antenna arrays, down-converters, modulators, amplifiers, etc., in a compact fixture. The paper uses, as a suggestive example, the evolution of the multi-port interferometric front-ends implementation from millimeter wave bulky components and systems to miniaturized and high-efficient ones. Circuit and system designs are carefully done to avoid (as much as possible) complicated calibration methods or difficult post-processing of baseband data. This requires an increased effort in design and fabrication, but it allows miniaturization, low-power consumption, while keeping very good overall performances. Useful and straightforward laboratory characterization techniques of circuits and systems are described in detail.

“…In this context a quasi-passive approach comes into play: The Six-Port architecture [11]. Initially developed for microwave network analysis, this approach has been addressed to generic direct-conversion system, receiver as well as transmitter in 1994 [12]- [14].The six-port technology utilizes only a few active components, e.g., a sinusoidal local oscillator and a low noise or power amplifier [15]- [20]. No additional active stages are required.…”

This paper presents a vector topology of a monolithic microwave integrated circuit (MMIC) capable of performing several radiofrequency (RF) functionalities essential for future wireless communications and geolocation in the millimeter frequency band. The proposed circuit can address several usage modes such as conventional frequency heterodyning for high-speed IQ modulation and demodulation. In addition, the device can be configured in six-port quadratic detection mode to achieve optimum power added efficiency (PAE). The topology developed in 65 nm FDSOI CMOS technology achieves broadband V-band frequency operation and combines vector precision for both high data rates and phase state determination. The results presented concern QPSK modulation schemes at data rates up to 4 Gbps as well as essential geolocation metrics such as time domain of arrival (TDoA) and angle of arrival (AoA). The combination of vector accuracy / PAE together with wide linear operating range makes this topology a viable candidate for next generation radio frequency systems. INDEX TERMSMonolithic microwave integrated circuit (MMIC), IQ modulation / demodulation, Millimeter wave, Six-port technology, Time domain of arrival (TDoA), Angle of arrival (AoA).
