Federal Custom Cable also provides 90 degrees Hybrid directional couplers, where the phase angle between the coupled output port signal and the primary line output signal equals to 90 degrees or simply 90 degrees out of phase. Hybrid couplers are generally 3 dB directional coupler (3 dB equates to half power), which divides power between the primary line output port and the coupled line output port. While providing 90 degrees phase angle difference between the two signals. Hybrid couplers are symmetrical electrically & mechanically, thus any one if the four ports can be designated as the input port and the same relationship between ports will remain.
Federal Custom Cable provides 90 degrees Hybrids that cover a wide range of frequencies from 0.5-18 GHz with average power up to 50 watts. 90 degrees Hybrids operate satisfactorily over the defined frequency band at a coupling ratio of approximately 3dB. They operate at a preset frequencies / Coupling of 0.5
