“…Furthermore, this device has an ability to measure two complex signals. This feature can be further applied in the purpose of signal modulation such as a quadrature phase shift keying (QPSK) and 16-quadrature amplitude modulation (16-QAM) as reported in [1][2][3][4][5].…”

Abstract. The design of the quadrature phase shift keying (QPSK) modulator by using a multi-port network is proposed in this article for the use in wireless communication applications. The multi-port network is in the form of multilayer microstrip-slot technology. This multi-port network is composed of three 3-dB rectangular-shaped directional couplers with virtual stubs and an equal power division divider with in-phase characteristic. The design is performed by applying a full-wave electromagnetic simulation software, CST Microwave Studio (CST MWS). Keysight's Advanced Design System (ADS) is applied in analyzingand evaluating the QPSK constellation of the proposed modulator. This comparatively small size of proposed design has been fabricated, and its wideband performance of 2 to 6 GHz is verified.

“…The reported narrowband designs utilizing three couplers and one power divider in [1][2][3][4] consider only single operating frequency of 60, 2.4, 2.5 and 7.5 GHz, accordingly. Meanwhile, there are improved bandwidth performances proposed in [5] and [6] with almost similar operating frequency of 3.1-4.8 GHz and 3-5 GHz, accordingly.…”

“…In [14,15] the demodulation performance is quantified over the entire operating frequency range, but with data rates much lower than in our experiments. A six-port demodulator supporting a 1.67 Gbps data rate was published in [6]. However, this is not a broadband design, as it only covers the range from 7 to 8 GHz.…”

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%.

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.
