WIDEBAND COMPACT RADIO FREQUENCY PHASE SHIFTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106116 titled 'WIDEBAND COMPACT RADIO FREQUENCY PHASE SHIFTER
Simplified Explanation
A hybrid switched-type phase shifter (STPS) combines E-type and T-type phase shifters to improve the stability of output signals across a wide frequency range. The hybrid STPS shifts the phase of input signals with different frequencies using varying phase shifts, resulting in reduced phase error during operation. The phase shifters may include capacitors and/or inductors, with shared circuitry to minimize the number of components and reduce circuit area. Stacking multiple inductors further decreases the circuit area required for phase shifting.

Original Abstract Submitted
a hybrid switched-type phase shifter (stps) may include the �-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.
