90 Degree Hybrids
90° Hybrids split an input signal into two equal amplitude output signals which are 90° out of phase from each other. Like in-phase dividers, 90° Hybrids may also be used as a power combiner.
180 Degree Hybrids
180° Hybrids split an input signal into two signals of equal amplitude and phase when the input signal is injected into the SUM port and two equal amplitude signals which are 180° out of phase with each other when injected into its DELTA port.
