KRYTAR launches new compact 3 dB, 90° hybrid coupler covering the 0.4 GHz to 7.125 GHz frequency range

05 April 2024

KRYTAR, Inc., a developer of ultra-broadband microwave components and test equipment announces a new 90° hybrid coupler that delivers 3 dB of coupling over the frequency range of 0.4 GHz to 7.125 GHz in a compact package.

KRYTAR’s family of 3 dB, 90° 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 90° hybrids are used in circuits requiring a balanced division of power into two transmission lines with 90° separation of phase. The 3 dB, 90° hybrids are often known as quadrature hybrids because a signal applied to any input will result in

KRYTAR’s new 90° Hybrid Coupler, Model 300407125, delivers exceptional versatility from 0.4 GHz 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°; isolation is greater than 19 dB; maximum voltage standing wave ratio: 1.3; and insertion loss of less than 1.8 dB.

In addition, Model 300407125 offers 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 inches (L) x 1.25 inches (W) x 0.52 inches (H), 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° Hybrid Couplers 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 beam forming, and electromagnetic compatibility testing environments. The compact size of these KRYTAR couplers is ideal for those dealing with limited space situations. The couplers can also be manufactured to meet military specifications.
