The Agilent/Keysight X752C is a WR-90 waveguide directional coupler designed for precision microwave measurements across the 8.2 to 12.4 GHz band. This conventional multi-hole construction coupler delivers 10 dB nominal coupling with ±0.4 dB mean accuracy and maintains directivity better than 40 dB across its entire frequency range. Low SWR performance—1.05 maximum on the primary line and 1.15 on the auxiliary line—ensures minimal signal degradation in cascade applications.
