90 Degree Hybrid Coupler to 20 GHz

Thu, 08/30/2001 - 9:29am
A special non-uniform tapered line design synthesized with a specially developed Krytar CAD program yields good amplitude and phase imbalance specifications. Model 1831 operates over the entire frequency band of 1.0 - 18 GHz. Coupling is 3 dB. Amplitude imbalance is ± 10 degrees maximum (tighter phase and amplitude imbalance available). Isolation is 17 dB minimum, and VSWR is 1.35 maximum. Insertion loss is 2.0 dB maximum. Standard connector is SMA female (N female available upon request). Power rating is 20 W average and 3 kW peak. Narrower frequency bands are available with improved specification. These hybrids are typically used in circuits requiring a balanced division of power into two transmission lines with 90 degrees separation of phase. Applications include signal splitters & combiners, balanced mixers, image-rejection mixers, phase shifters, diplexers, switches, and antenna feed networks.
