Abstract-A short review of the multiport (six-port) theory for modern applications in downconversion, direct demodulation or modulation of RF signals, and new measurement techniques for localization is presented in this paper. More than four decades ago, the circuit was developed for low-cost S-parameter measurements of microwave circuits. The modifications required to transform original six-port instrument function to radio function was not obvious in the beginning. In this purpose, several innovations have been implemented during the last two decades. Implementations of the circuit in various mature fabrication technologies, covering frequencies from microwave to millimeter wave spectrum, are presented and discussed. Multiport receiver calibration and impairment mitigation techniques are also proposed at frequencies where analog-to-digital converters and digital signal processing are available.

“…Simulations have also been performed for a V-band multiport heterodyne receiver [5]. The multiport technology allows improved results in terms of conversion loss and requires a reduced LO power compared to the conventional methods (as low as −20 dBm to perform an efficient frequency conversion), as it has recently been demonstrated in [6].…”

“…Figure 2 shows the equivalence with conventional I/Q mixer architecture. The millimeter-wave multiport in conjunction with a local oscillator and two IF differential amplifiers (IFDA) will be used in order to obtain two quadrature IF signals, avoiding the use of two costly millimeter-wave mixers and reducing the power consumption [5]. It is to be noted that these IF circuits will realize additional filtering functions.…”

“…These modulations, such as M-ary quadrature amplitude modulation (QAM) and M-ary phase shift keying (PSK), will increase the spectral efficiency. Simulations of a 60 GHz high-speed multiport heterodyne receiver have been recently published [5]. A bit-rate up to 400 Mbps has been achieved using a 16 QAM modulation for an IF of 900 MHz.…”

Recommended by Daniel IancuMillimeter-wave multiport transceiver architectures dedicated to 60 GHz UWB short-range communications are proposed in this paper. Multi-port circuits based on 90• hybrid couplers are intensively used for phased antenna array, millimeter-wave modulation and down-conversion, as a low-cost alternative to the conventional architecture. This allows complete integration of circuits including antennas, in planar technology, on the same substrate, improving the overall transceiver performances.

A new front‐end architecture dedicated to 60 GHz high‐speed short‐range communications is proposed. Multiport circuits based on hybrid couplers are intensively used for both phased antenna array and down‐conversion. The front‐end, integrated in planar technology on ceramic substrate, use several IF quadrature conversion circuits, corresponding to multiple directions of arrival. © 2008 Wiley Periodicals, Inc.
