“…However, the presented QPSK constellation is only verified for selected frequency of 5, 6.5 and 8 GHz. Then, impressive miniaturization and wideband designs achieved by designing at millimeterwave region have been demonstrated in [8] and [9] with the operating frequency of 23-31 GHz and 24-30 GHz, respectively. Nevertheless, these designs require high precision and high-end fabrication facility and measurement equipment, which may not be available in most research laboratories.…”

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 multi-port architecture was very similar to the original approach and a calibration process was needed to perform measurements. The idea of a multi-port interferometer with no need of calibration appeared in 2001 (Tatu et al, 2001). Especially for microwave and millimeter wave frequency, the multi-port successfully replace the conventional I/Q mixers in the receiver front-ends.…”

“…At the beginning, a multi-port circuit was designed at Ka-band frequencies, in MHMIC and MMIC technologies, to be used in a direct conversion receiver for high speed QPSK communications (Tatu et al, 2001). The circuit was first designed and fabricated in hybrid technology, on a 250 µm ceramic substrate with a relative permittivity ε r = 9.9.…”

“…An obvious advantage of the device is that magnitude and phase of two complex signals can be measured accurately by heterodyning receiver technology. It is applied not only to the measurement of S-parameter of high-power transistors [4], but also to designing microwave receivers [5] and vector voltmeters. In the field of microwave measurement, a six-port device can be employed in broadband nonlinear system measurement.…”

Abstract-A compact fully integrated wideband six-port device composed of a suspended stripline Wilkinson power divider and three bias stripline of 3-dB quadrature directional couplers is presented. In order to integrate a six-port circuit, a multilayer circuit structure has been adopted by the via hole interconnection at the output port of the divider. The 3-dB quadrature directional coupler is composed of two 8.34-dB quadrature directional couplers by series connection. In this way, the six-port circuit structure is simplified and reduced. A multisection impedance match structure has been adopted in the suspended stripline Wilkinson power divider to achieve ultra-wide frequency band. In the experiment, the fully integrated six-port device has obtained good measurement result. It is superior to other present six-port networks in microwave performance with the same dimension.
