KRYTAR, Inc., a leader in the design and production of ultra-broadband microwave components and test equipment has introduced a new 180-Degree Hybrid Coupler that delivers 3 dB of coupling over the frequency range of 0.4 to 7.125 GHz in a compact package. KRYTAR’s family of 3 dB, 180-Degree Hybrid Couplers perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks used in a wide range of commercial and military applications.
KRYTAR’s new 180-Degree Hybrid Coupler, Model 400407125, delivers exceptional versatility from 0.4 to 7.125 GHz with excellent phase and amplitude matching. Typical specifications include 3 dB Coupling; Amplitude Imbalance: ±0.7 dB; Phase Imbalance is ±10 degrees; Isolation is >15 dB; Maximum VSWR: 1.4; and Insertion Loss of <2.9 dB. The 180-degree hybrids (also referred to as the “rat race” couplers) are four-part devices that are utilized to either equally divide an input signal or to add-up two fused signals. An extra benefit of this hybrid coupler is to alternately offer an equally-divided 180-degree phase-shifted output signals.
Broadband hybrids have traditionally been developed in 90-degree configurations with less bandwidth generally available for the greater phase relationship of a 180-degree hybrids. Systems such as antenna beamforming networks can be designed more efficiently with KRYTAR 180-degree hybrids since less components are required to recombine divided signals.
In addition, Model 400407125 offers Input Power Rating of 20 W average and 3 kW peak. The hybrid coupler comes with industry-standard SMA Female Connectors. The compact package measures just 10.25 inches (L) x 1.35 inches (W) x 0.52 inches (H), and weighs only 11.0 ounces. Operating temperature is -54° to 85° C. This coupler is typically available from stock to 30 days, ARO..
KRYTAR 180-Degree Hybrid Couplers offer simple solutions in many applications within those frequency bands including electronic warfare (EW), commercial wireless, 5G and 5G NR (New Radio), Wi-Fi 6 and Wi-Fi 6E, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. The compact size of these KRYTAR couplers are ideal for those dealing with limited space situations. The couplers can be also be manufactured to meet military specifications.
