“…Some published works are not strictly multi-band [18,24]; other are multi-band but only validate the demodulator for a single frequency [23,26]; and other prove the multi-band behaviour but do not quantify the quality of the demodulated signal [22]. In [21,25] the demodulation performance is quantified over the entire operating frequency range, but with data rates much lower than in our experiments. Recently, a six-port demodulator supporting a 1.67 Gbps data rate has been published [27].…”

Abstract-This paper presents a software defined radio six-port receiver for a novel broadband mobile communications system. The prototype covers the frequency range from 0.3 GHz to 6 GHz, and operates with up to 100 MHz-wide channels. The multi-band and multi-mode demodulation capabilities of the six-port architecture have been experimentally demonstrated. The six-port receiver has been satisfactorily proved for high data rates (up to 93.75 Mb/s, limited by the available test instruments). An efficient six-port autocalibration method suitable for large instantaneous bandwidth systems is presented and validated.

“…This is a high dynamic range compared with six-port receivers based on zero-biased detector diodes. For example, a 37.3 dB dynamic range at 2.4 GHz is measured in [14], despite that the response of the detectors has been linearised using software techniques. On the contrary, we do not use any diode linearization technique.…”

Abstract-The six-port architecture reemerges from the search of low-cost, multi-band and multi-standard transceivers. Its inherent advantages, especially its broadband behavior, make this a structure a good candidate to implement a Software Defined Radio (SDR). However, broadband six-port network designs lead to large size circuits, especially for operating frequencies in the lower gigahertz region. New technologies must be explored in order to achieve compact size and low-cost productions for configurable radio terminals and mobile communication applications. In this paper, the Low Temperature Co-fired Ceramic (LTCC) technology is proposed for implementing a broadband six-port receiver. A compact (30 mm × 30 mm × 1.25 mm) four-octave LTCC six-port receiver is presented.Experimental demodulation results show a good performance over the frequency range from 0.3 to 6 GHz. The demodulation of up to 15.625 Msymbol/s signals, i.e., 93.6 Mbps for 64-QAM, has been satisfactorily performed, with a measured Error Vector Magnitude (EVM) value of 3.7%.

“…There are not many experimental data about dynamic range in six-port receivers. A 37.3 dB dynamic range at BER = 10 −3 is reported in [20], where a 0.8-2.4 GHz six-port receiver based on zero-biased detector diodes is presented. It is worth to mention that a diode linearization software is used in [20] to extend the square law region, while we do not use any diode linearization technique.…”

Abstract-This paper presents an experimental performance comparison among three RF architectures that are very suitable for Software Defined Radio (SDR) implementation: zero-IF, low-IF, and six-port network. A six-port receiver and a dual zero-IF/low-IF receiver have been developed for this purpose. Six-port receiver is a very promising and flexible RF architecture for the low-cost implementation of integrated microwave and millimeter-wave systems. Competitive advantages such as ultra-broadband behavior, low-cost, reconfigurability, and low power consumption, point to the six-port architecture as a good candidate to implement a SDR. However, two issues on broadband six-port receivers require intensive research: dynamic range extension, and miniaturization. In this paper, two solutions are proposed to solve these problems: the use of biased detector diodes for dynamic range extension, and the use of low temperature co-fired ceramic (LTCC) technology for six-port reduction. The measurement results indicate that the six-port receiver shows high potential benefits and advantages compared to conventional zero-IF and low-IF receivers. In addition, the capability of the six-port architecture to operate as both zero-IF and low-IF receivers has been experimentally demonstrated for the first time.
