Abstract: A hybrid switched-type phase shifter (STPS) may include the π-type phase shifters and T-type phase shifters to provide more stable output signals over a wide frequency range. The hybrid STPS may provide output signals based on shifting a phase of the input signal having different frequencies across the frequency range by different phase shifts with relatively similar phase drifts resulting in a reduced phase error during operation. In some cases, the phase shifters discussed above may also include a number of capacitors and/or inductors. In some embodiments, a circuitry or layout of the phase shifters may be shared to reduce a total number of capacitors and therefore reduce a circuit area of the hybrid STPS. Moreover, stacking at least two inductors of the hybrid STPS may also reduce a circuit area for shifting the phase of the input signal by the desired phase shifts across the frequency range.
