400W 13.75-14.5GHz Waveguide High Power Isolator for BUC
Product Introduction
This field‑validated WR75 waveguide high‑power isolator with sampling port is purpose‑built for demanding Ku‑band high‑power microwave systems covering 13.75‑14.5 GHz. It safeguards microwave sources and power amplifiers against damaging reflected power, while the integrated coupled sampling port enables real‑time signal observation for system supervision.
Across its full operating bandwidth, this isolator delivers robust electrical performance: maximum VSWR of 1.25, insertion loss down to 0.3 dB, and minimum 20 dB isolation. It withstands up to 400 W forward power and 200 W reverse power, fitting rigorous high‑power transmitter deployments. The onboard 40 dB sampling port supplies low‑level signal tapping for monitoring, testing and system control without interfering with the primary signal path.
Constructed for dependable field integration, the unit adopts WR75 waveguide with FBP120 cover flange to guarantee accurate, repeatable assembly. Its aluminum housing receives internal chromate‑conversion treatment for corrosion resistance and external anti‑corrosive black paint for harsh‑environment durability. Two FBM120 O‑rings are included as standard accessories to achieve dependable flange sealing for long‑term stable operation.
