DIRECTIONAL COUPLER

/ KR

ECHO microwave manufactures single and dual-directional and hybrid couplers that operate across our standard frequency range from 698 to 2700MHz. In addition to this frequency range, we can design and manufacture directional couplers to specification across 10MHz to 18GHz.

Coupling values for 6/ 7/ 8/ 10/ 13/ 15/ 20/ 25/ 30dB
Low Passive Intermodulation(PIMD)
20dB Directivity
