“…The software, implemented in Matlab, is applied in a personal computer to regenerate the I-Q components of the original signal. For the six-port receiver calibration, it has been used the conventional six-port auto-calibration method based on training sequence described in [12][13][14][15][16][17][18][19]. The quality of the demodulated signal will be measured in terms of the EVM (Error Vector Magnitude).…”

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.

“…In [19], modified series diamond stubs were used along with power divider (PD) and branch line couplers, achieving 75 FBW and a size of about 0.34 λ 2 . Multilayer technology is employed in [20–22], utilizing the multisectional approach for hybrid coupler (HC) and PD. Therein, an improvement in FBW from 120 to 150 is reported, but the compactness is partly sacrificed as the size is increased to about 3.48 λ 2 .…”

In this paper, a new design approach for the six-port (SP) junction is introduced. The proposed design includes a generalized broadband matching and smooth miniaturization scheme and is extendable for any passive multiport structure. A multilayer technology and a microstrip to slot coupling operation are employed for the designed SP, which comprises power divider and three hybrid couplers. The conducted measurements of the constructed SP junctions validates the design approach. Optimal performance of the SP network in terms of miniaturization, bandwidth, and response accuracy were obtained for the 5G low band.

“…In the search of a universal and flexible radio platform, capable of operating with multiple standards in multiple bands, several RF architectures have been studied [2][3][4]. Two of the best candidates to implement a SDR are the direct frequency conversion architecture, also named zero-IF, and the low-IF architecture.…”

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.
