Manufacturer: KRYTAR, Inc.
Product Type: 3dB 180-Degree Hybrid Coupler
Frequency Range: 7.125GHz to 15.35GHzCoupling: 3dB
Standard Connector: SMA Female
Description: Compact four-port hybrid coupler for equal-power RF signal splitting and combining with a controlled 180-degree phase relationship.
The KRYTAR 407125-1535 is a four-port, 3dB 180-degree hybrid coupler operating from 7.125 to 15.35GHz. Its frequency range covers the upper C band, X band and part of the Ku band, making it suitable for radar, satellite communication and microwave test systems.
The hybrid divides an input signal into two nominally equal-amplitude outputs. Depending on the selected input port, the outputs can provide an in-phase or 180-degree phase relationship. It can also operate in reverse as a coherent RF signal combiner.
Compared with wider-band hybrid couplers, the 407125-1535 provides tighter amplitude balance, phase balance and insertion-loss specifications within its defined operating range.

Choose the 407125-1535 when the system operates within its narrower frequency range and requires SMA connectors, lower insertion loss or tighter amplitude and phase balance.
Choose the 4030320 when continuous coverage from 3 to 32GHz is more important than the tighter in-band specifications of the 407125-1535.
