Thermally Stable Dielectrics: Foam-based insulating materials maintain impedance stability across temperature ranges from -55°C to +125°C.
These innovations enable coaxial systems to support frequencies up to 50 GHz while withstanding harsh environmental stressors.
Diverse Component Portfolio Addresses Complex Architectures
Beyond basic transmission lines, coaxial component ecosystems now offer:
Waveguide Transitions: Seamless integration between coaxial and waveguide systems for hybrid RF front-ends.
Hybrid Couplers: 90-degree and 180-degree phase-shift models facilitating MIMO antenna array synchronization.
Broadband Attenuators: Temperature-compensated designs ensuring consistent signal levels in variable-load scenarios.
Customizable Bends: Mitered 45°/90° elbows minimizing reflection losses in space-constrained installations.
Such versatility allows engineers to construct complete signal chains without compromising on footprint or performance.
