RF Couplers: Directional & Hybrid
Source broadband directional couplers and custom hybrid couplers for spacecraft, electrical ground support equipment (EGSE), ground-segment and RF test applications. Compare standard 8–40 GHz directional configurations or discuss a custom hybrid designed around your frequency band, phase relationship and RF interfaces.
