LHF series cables provide low insertion loss within the current industry and have excellent mechanical phase, temperature phase, and attenuation stability. Currently, the highest operating frequency of this series is 67GHz. It uses ultra-low-density PTFE medium and silver-plated copper tape. It is formed by wrapping and shielding. This series of products are widely used in military radars, electronic countermeasures, and high-power applications with highly demanding requirements;
