“…Besides, between the input and output ports of a CL-TRD coupler, DC blocking is inherent. Recently, several researches have been done on the TRD-based RTPS [17][18][19]. However, the phase shift ranges of these reports are limited to less than 180 • .…”

In this paper, a full-360 • reflection-type phase shifter (RTPS) using a trans-directional (TRD) coupler with multi-resonance loads is presented. It features the characteristics of wide bandwidth, small size, wide phase shifts with a compact structure and inherent DC blocking. Influences of the multi-resonance loads on the phase shifts and insertion losses of the RTPS are analyzed, and design procedures are given for guidance. For validation, a prototype is designed at 2 GHz. The overall size is 0.56λ g × 0.17λ g . Measured results show a bandwidth of 20% under the criterion of more than 10-dB return loss. Meanwhile, a relative phase variation of 425 • with a maximum insertion loss of 3.6 dB is achieved when the varactor capacitance is varied among 0.35 pF ∼ 3.2 pF.

A wideband tunable balanced phase shifter is achieved by utilizing varactor-loaded coupled lines (VLCLs)-embedded multistage branch-line structure. The tunable phase shift with low in-band phase deviation is attributed to the regulation in phase shift of the VLCLs and the horizontal microstrip lines in series. The wideband differential-mode (DM) impedance matching and common-mode (CM) suppression are due to multiple DM transmission poles and CM transmission zeros, which are brought about by the cascade of VLCLs and a microstrip line with short-circuited stubs in the DM-equivalent circuit and open-circuited stubs in the CM-equivalent circuit, respectively. Compared with the state-of-the-art tunable balanced phase shifters, the proposed design not only has the advantages of wide operating bandwidth (BW) with low in-band phase deviation but also has low insertion loss and easily fabricated structure. Theoretical analysis and design procedure were conducted, resulting in a prototype covering the frequency of 1.8 GHz. This prototype offers a tunable phase shift capability ranging from 0° to 90°. The prototype exhibits an operating BW of 45%, with a maximum phase deviation of ±6°. It also achieves a 10 dB DM return loss and CM suppression, while maintaining a maximum insertion loss of 2.5 dB.
