KRYTAR, Inc., a leader in the design and production of ultra-broadband microwave components and test equipment, announced a new 90-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, 90-degree hybrid couples perform many functions, including splitting and combining signals in amplifiers, switching circuits and antenna beamforming networks used in a wide range of commercial and military applications. KRYTAR 90-degree hybrids are used in circuits requiring a balanced division of power into two transmission lines with 90-degree separation of phase. The 3 dB, 90-degree hybrids are often known as quadrature hybrids because a signal applied to any input, will result in two equal amplitude signals that are both quadrant (90 degrees separated from one another). The signals at the outputs are attenuated by three decibels (3 dB) and have a 90 degree phase difference with respect to each other.

KRYTAR’s new 90-degree hybrid couple, model 300407125, delivers exceptional versatility from 0.4 to 7.125 GHz with excellent phase and amplitude matching. Typical specifications include 3 dB coupling; amplitude imbalance: ±1.0 dB;phase imbalance is ±5 degrees; iolation is >19 dB; maximum VSWR: 1.3; and insertion loss of < 1.8 dB.

In addition, Model 300407125 offers an input power rating of 20 W average and 3 kW peak. The hybrid coupler comes with industry-standard SMA female connectors and optional N-type female connectors. The compact package measures just 8.15 x 1.25 x 0.52 in. and weighs only 8.3 ounces. Operating temperature is -54° C to 85°C. This coupler is typically available from stock to 30 days, ARO.

KRYTAR 90-Degree hybrid coupler offer simple solutions in many applications within those frequency bands including electronic warfare, commercial wireless, 5G and 5G New Radio, Wi-Fi 6 and Wi-Fi 6E, satcom, radar, signal monitoring and measurement, antenna beamforming and EMC testing environments. The compact size of these KRYTAR couplers are ideal for those dealing with limited space situations. The couplers can also be manufactured to meet military specifications.
