“…The LC values of a single resonant circuit and a composite resonant (CR) circuit from the phase shifter equations can be obtained. 11 A modified composite resonant (MCR) circuit is proposed by improving the shortcomings of using chip devices for these resonant circuits. For demonstration purposes the proposed phase shifter using LC resonant circuits are designed with single, composite, and modified composite circuits at a 90 phase shift.…”

This article proposes a new wideband 90°phase shifter, aligning the phase slope between a reference line and a mainline to reduce the slope deviation. The design theory of the proposed phase shifter using a modified composite resonant circuit is converted from the LC resonant circuit to the transmission line for easy fabrication. To validate the design theory, the conventional and proposed phase shifters are designed, fabricated, and measured. The fractional bandwidth of the proposed phase shifter is over 77% in terms of the magnitude and phase difference. Therefore, the measurement results agree well with the design theory within a 0.5 dB insertion loss and ± 10° phase deviation, except for fabrication errors.

This paper proposes a novel Doherty combiner that uses a series and parallel resonant circuit for wideband. Unlike conventional combiners, the aim of the proposed combiners is to extend bandwidth for not only the magnitude bandwidth, but also phase balance by employing series and parallel resonant circuits at the output impedance of the peaking amplifier. Considering the load impedance of the peaking amplifier, the Doherty combiners were analyzed in the theory of this study by deriving the series and parallel resonant circuit values. The output phase balances are determined for the targeted bandwidth to achieve uniform phase balance in the proposed combiner I using a series resonator. For better magnitude bandwidth, the slope of reflection coefficient (Γ) at port 3 in the combiner II using series resonator was derived using the derivative of Γ with respect to ω. Experimental results show that the proposed combiner I has 63.5% magnitude fractional bandwidth (FBW) and 118% FBW with the phase balance at ±2.5°. The proposed combiner II also has 85% magnitude FBW and 118% FBW with the phase balance at ±2.5°.
