“…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 detection circuit is designed to cope with a wideband operation (23 to 31 GHz) using HSCH-9161 type zero-bias Schottky diodes. The MMIC multi-port module is fabricated on a 100 micron TriQuint's GaAs substrate with a relative permittivity ε r = 12.9 (Tatu et al, 2002). Three different implementations of the 90° hybrid coupler in a frequency range of 6 GHz, between 24 and 30 GHz, with distributed parameters, discrete components, and a combination of both methods, are realized and compared.…”

“…The six-port technology, widely recognized in microwave low-cost circuit characterizations [5][6][7][8][9] has been used as an unconventional technique to perform frequency down-conversion [10][11][12][13][14][15][16][17]. The millimeter wave frequency conversion is performed using a passive circuit, multiport, and related power detectors, avoiding the conventional millimeter-wave active costly mixers.…”

Abstract-This paper presents a new implementation of a millimeter wave heterodyne receiver based on six-port technology. The six-port circuit is designed using three hybrid couplers H-90 • and a new ring power divider. For the characterization of the circuit, several six-port two-port measurement configurations were designed and fabricated on the same wafer along with calibration standards. The new six-port architecture evaluation based on q i points location demonstrates wideband performances and high coupled-port phase and amplitude balance in the 57-65 GHz frequency band. The six-port model based on S-parameter measurements is then implemented in ADS software, for realistic advanced simulation systems of a short-range 60 GHz wireless link. The millimeter wave frequency conversion is performed using a six-port down-converter. The second frequency conversion uses conventional means due to the low IF frequency value. The demodulation results of a V-band QPSK signal for high data rate from 100 to 1000 MBits/s are presented and discussed. The results of the Bit Error Rate (BER) analysis demonstrate that the proposed architecture can be successfully used for high speed wireless link transmission at 60 GHz.
