Abstract We propose a phase noise suppression scheme for RF signal remote fiber transmission based on a photonic phase shifter. Phase noise induced by the temperature variation and mechanical perturbation is suppressed automatically and effectively through a feedback network.

We propose an S-band active phased array antenna (APAA) with analog phase shifters (PSs) that use double-balanced mixers (DBMs). The quadrature phase shift keying modulator integrated circuits (ICs) used as the phase shifters can control both the amplitude and phase of the input signal continuously and independently by using the control voltages.

This paper proposes a novel circuit configuration of an even harmonic quadrature mixer (EHQMIX) for direct conversion receivers. In this EHQMIX, a 90 degree phase shifter consists of balance type high pass and low pass filters, and it does not require any circuits connecting to the ground plane. So this configuration is suitable for low cost monolithic

360° Tunable Balanced Filtering Phase Shifter With Reflectionless and Wide Stopband Characteristics
International Journal of Circuit Theory and ApplicationsABSTRACT A tunable balanced filtering phase shifter with reflectionless and wide stopband characteristics is presented in this paper. The proposed circuit consists of a six‐port balanced‐to‐unbalanced (BTU) quadrature coupler, two identical varactor‐tuned reflective loads, and two absorptive filtering networks.

The cross talk and power consumption of the 2 × 2 optical switch is a key metric in the design of large-scale photonic integrated circuits (PICs). We build a theoretical model of a 2 × 2 Mach–Zehnder interferometer (MZI) optical switch, taking into account both imbalances in the arm loss and the coupler splitting ratio.
