The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating. Above all, engineers and students will love this handy and helpful tool. Content Tools Reflection measurement (Return loss - VSWR) Frequency wavelength (Wavelength calculation) Signal delay (Signal delay - Dielectric constant - Velocity in % of speed of light) Impedance dimension (calculation of impedance of coaxial line) dB Calculator (dB Ratio / Watt - dBm) RF Assembly Calculator (comparison of up to three HUBER+SUHNER RF cables) Used formulas are explained in detail by meaningful pictures. Products Provides an overview of HUBER+SUHNER products such as cables, connectors, antennas, lightning protectors and passive components with the help of the product catalogues.
