A 6-bit active digital phase shifter
IEICE Electronics Express, 2011 This paper presents the design of a 6-bit active digital phase shifter in 0.18-µm CMOS technology. The active phase shifter synthesizes the required phase using a phase interpolation process by adding quadrature phased input signals. It uses a new quadrature all-pass filter for quadrature signaling with a wide bandwidth and low phase error.

A precise digital phase shifter using a phase-locked loop
Electronics Letters, 1978 A phase-locked loop containing a voltage-controlled oscillator (v.c.o.) synchronised to a harmonic of its fundamental output frequency may be used to form an attractive digital phase shifter providing low phase error with relatively simple circuitry and control requirements.

Low Loss Multi-Channel Communication Combiner for Cellular Applications
IEEE Access, 2023 The increasing demand for cellular communication channels calls for multichannel solutions. Using one antenna for each channel results in a high density of antennas at the compact cellular station front, which generates inter-channel interference.
