WG to Coaxial Adaptor (End Launch)
Waveguide to Coaxial Adaptors (End Launch) are precision microwave components designed to provide efficient signal transition between rectangular waveguides and coaxial transmission lines. These adaptors enable RF and microwave signals to be transferred from waveguide systems to coaxial connectors while maintaining excellent impedance matching, low insertion loss, and superior signal integrity. They are widely used in radar systems, satellite communication, aerospace applications, defense electronics, microwave testing laboratories, RF measurement systems, and high-frequency communication networks.
At SRFS Teleinfra, we manufacture premium-quality WG to Coaxial Adaptors (End Launch) engineered for high-frequency microwave applications. Our adaptors are manufactured using precision-machined waveguide structures and high-performance coaxial interfaces to ensure low VSWR, excellent return loss, and reliable RF performance across demanding communication environments. Available with SMA, K (2.92mm), 2.4mm, 1.85mm, and 1.0mm connector interfaces, these adaptors support a wide range of waveguide bands and microwave frequencies.
WG to Coaxial End Launch Adaptors are commonly used in microwave transmitters, radar systems, satellite ground stations, EMC testing facilities, antenna measurement systems, RF calibration setups, and laboratory instrumentation where accurate signal transition is critical.
