Datasheet: 180 Degree Hybrid Couplers: Control Signals From 1 to 26.5 GHz

Hybrid Couplers perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks. Krytar Hybrid Couplers deliver this versatility from 1 to 26.5 GHz with excellent phase and amplitude matching.

Hybrids are four-port components, with dual input and output ports. A signal applied to the sum (?) input port produces two output signals of matched amplitude and phase. Each output level of a Krytar 180 degree hybrid is 3 dB lower (less the insertion loss through the hybrid) than the input level. Signals applied to the difference (?) input port produce two equal-amplitude output signals that are 180 degrees out of phase with each other. This characteristic makes such hybrid circuits ideal for reducing noise in amplifiers via feedback combining techniques or for merging multiple signals from arrays. (See table 1 for complete specifications of Krytar 180 degree hybrid couplers).
