Abstract
Systems and methods for providing phase shifting in antenna arrays, such as phased antenna arrays of 5G cellular technology, are disclosed. In one aspect, an example phase shift module may include a phase shifter and a frequency multiplier. The phase shifter is configured to receive an LOcal oscillator (LO) signal and output a signal that is phase-shifted by a desired phase shift with respect to the LO signal. The frequency multiplier may be an enhanced frequency multiplier, configured to use not only the phase-shifted signal but also an inverted version of the phase-shifted signal to generate a frequency-multiplied signal having a frequency that is a multiple of the LO signal frequency. In another aspect, an example phase shift module may be configured to apply to an LO signal a phase shift that takes into consideration variations of phase shift over temperature.
