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.

The increasing use of ultra-broadband microwave systems, and the emerging wireless communications systems, including mmWave, has created a need for broadband 90-degree hybrids with tight output amplitude and phase tracking. KRYTAR 90-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.
