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.

“…This contributes to the prosperity of the research in CMOS MMW circuit designs. As a result, in recent years, MMW transmitters and receivers are reported in CMOS technologies including multi-port transceiver [199], direct-conversion transceiver [191,200], Doppler radar transceiver [201][202][203], phased-array transceiver [204,205] and differential transceiver [166].

“…While suited to frequencies in the range of 20GHz, the current-mode phase shifter in [1] would call for impractically small capacitor values at 60GHz. Also, the microwave couplers proposed in [5] require a large area and accurate impedance matching. To obtain a reasonable image rejection as well as practical component values, a 2-stage polyphase filter is used in this design.…”

Recent work on receivers for the 60GHz band has considered various frequency plans to ease the design of the building blocks, particularly the local oscillator (LO) and the frequency dividers [1][2][3]. A natural choice of the LO frequency in a heterodyne system is half of the input frequency as it places the image in the vicinity of zero while greatly simplifying the design and distribution of the LO and divider signals [4]. Unfortunately, a simple heterodyne chain consisting of a single RF mixer and quadrature IF mixers suffers from an additional image introduced by the third harmonic of the LO in the RF mixing operation, which flips the signal spectrum horizontally and superimposes it on the original downconverted spectrum. Since the third harmonic of the LO is only 9.5dB lower, this corruption proves serious in modulation schemes having asymmetric spectra, e.g., FM, QPSK, and QAM. This paper describes a heterodyne receiver architecture that incorporates a 30GHz LO without quadrature phases and resolves the issue of the third harmonic of the LO as well. The architecture thus lends itself better to integration and signal distribution while consuming lower power.With a 30GHz LO, the switching of the RF mixer convolves the +90GHz harmonic with the signal spectrum at −60GHz, thus translating this spectrum to +30GHz. This component is only 9.5dB below the desired component, which is the result of translating the +60GHz signal spectrum to +30GHz. Any attempt to linearize the LO port of the mixer so as to raise this ratio substantially degrades the conversion gain and increases the noise figure.As shown in Fig. 9.6.1, the proposed receiver performs quadrature separation in the RF path and downconverts the signal to 30GHz and subsequently to baseband. Figure 9.6.2 illustrates the operation by showing the spectra at various points along the receiver chain. By virtue of quadrature separation, the positive frequency content of the signal is removed; i.e., mixers MX 1 and MX 2 sense a complex RF signal, [I 1 , Q 1 ], that contains energy only around −60GHz. These mixers are also driven by the 30GHz LO frequency and its third harmonic. Upon mixing, MX 1 and MX 2 produce output currents that, viewed as a complex signal [I 2 , Q 2 ], contain (1) the main component around −30GHz, (2) a replica at +30GHz that is 9.5dB lower in magnitude, and (3) a component shifted to −90GHz. Since the output currents of these mixers flow through load tanks resonating at 30 GHz, the −90GHz component is attenuated by 25dB. Consequently, MX 3 and MX 4 sense a complex IF signal that carries the main signal spectrum, S 1 , at −30GHz and its attenuated replica, S 2 , at +30GHz. The IF mixers therefore generate a complex baseband signal, [I B , Q B ], equal to the sum of S 1 and S 2 . Note that, even though the RF signal spectrum is asymmetric, the complex processing makes it possible for S 2 to enhance S 1 rather than corrupt it.In the presence of mismatches in the polyphase filter, the complex spectrum sensed by MX 1 and MX 2 contains a small rep...
