MIcable releases an ultra-wideband bi-directional coupler covering 10MHz~67GHz, with maximum coupling of 13dB @1~67GHz and 56dB @0.01~1GHz. The Insertion loss is 2.8dB max. over the full band, with tested performance below 2.0dB. In addition to excellent VSWR performance and directivity of 15dB, the coupler employs a fully shielded mechanical configuration to suppress microwave leakage, achieving approximately 100 dB of shielding effectiveness. This component is ideally suited for ultra-wideband RF test systems and microwave & millimeter-wave test instrumentation.
