“…The higher the frequency, the smaller the passive circuit and the easier the integration in a MMIC design [23,24]. However, for operating frequencies in the lower gigahertz region, a broadband design in conventional technology leads to large dimensions, which could be prohibitive, for example, for mobile communication applications.…”

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.

“…The six-port technique was demonstrated to be a suitable option as the ratio of complex amplitude measurements in [2][3][4]. Many microwave applications directly or indirectly require the determination of phase differences between two input microwave signals over a specified frequency band, such as microwave vector network analyzers (VNA) [5], direction finding [6,7], position sensors [8], frequency measurement [9], digital signal demodulation [10], and other applications [11][12][13][14][15][16]. The six-port technique adopts a zerointermediate frequency architecture, whose advantages are listed: no mixer, no image frequency, high integrated level, low cost, reconfigurability, etc.…”

Abstract-This paper presents a six-port network over an ultrawideband (UWB) of 2-8 GHz. Its key component is the six-port junction, which consists of a Wilkinson power divider and three 3-dB quadrature couplers. This six-port junction is accomplished in a low dielectric constant substrate (Rogers RT/duroid 5880). Multi-section impedance transformation is applied in the power divider, and the quadrature coupler is realized by using two 8.34 dB couplers in tandem. An ultra-wideband operation of the six-port junction is verified by full electromagnetic simulations and measurements. The results show that the designed devices exhibit good performance across 2-8 GHz band: the return losses at input ports are higher than 15 dB, the insertion losses from input ports to the remaining ports are 7.2 dB ± 1.7 dB, the isolation between two input ports is greater than 20.5 dB, and the maximum phase difference compared with the theoretical behavior between two test ports is 10 • . For the manufactured six-port junction, a six-port phase measurement system and a calibration technique based on support vector regression (SVR) are introduced. Results show that the SVR model can achieve a mean phase error of 1.5274 • .

“…The main characteristic of the six-port architecture is its extremely large bandwidth, which involves multi-band and multi-mode capabilities. Six-port networks can operate at very high frequencies, being a serious alternative for millimetre-wave frequencies and large relative-bandwidth applications [7][8][9]. But since the six-port receiver is said to be a good solution for the multi-band demodulation of high-speed signals, not many experimental demodulation results have been published up to now.…”

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.
