Bi-Directional Couplers

555 Series Couplers available in 3, 6, 10, 20, 30, and 40 dB coupling values

Mi-Wave’s 555 Series Bi-directional couplers are broadband, broadwall wavegugide type. The 556 are split block type components with a multi-hold directivity. The 555 Series couplers are available in 3, 6, 10, 20, 30, and 40 dB coupling values for standard waveguide bands from 18 to 220 GHz.

The 555 Series Bi-directional Couplers are used in applications that require precise sampling of both incident and reflected energy. The 3 dB couplers are especially useful in balanced mixer work where broadband power division of RF and LO signals is required to supply both sides of a balanced mixer unit. The 3 dB bi-directional couplers can provide full bandwidth power division
