High power directional couplers

May 10, 2018 // By Jean-Pierre Joosting
High power directional couplers from RLC Electronics offer accurate coupling (±1.0 dB), low insertion loss (0.1 to 0.35 dB maximum) and high directivity (>14 dB at 18 GHz).

These high power couplers are offered with 500 to 1000 W average power handling up to 18 GHz, as well as 100 W versions up to 40 GHz. The standard units are optimized for 2 octave bandwidths and are available with a choice of coupling values (30, 40 or 50 dB). RLC can utilize SC or 7/16 connectors on the main line, should this be needed to meet customer designs. These units are ideal for sampling forward and reflected power with a negligible effect on the transmission line and very low intermodulation products.
