Waveguide to Coaxial Adapter (Right Angle)(End Launch)

Available in aluminum or copper with SMA, N, K, 2.4mm, 3.5mm, TNC, and 1.85mm coax connectors. Custom flange types (UG, CPR, cover, groove), finish (silver/gold plating), straight or right-angle configuration, and power handling levels (continuous wave from 35W to 2kW, peak up to 6kW). Ideal for radar systems, satellite ground stations, 5G mmWave testing, microwave test & measurement, telecom infrastructure, and VNA calibration. Achieves low VSWR as low as 1.10:1 across full waveguide bandwidth from 1.12 to 110 GHz.

Rectangular waveguide-to-coaxial adapters are the most basic and widely used mode conversion components in microwave and millimeter-wave systems. They are designed to achieve low-loss, low-VSWR signal conversion between standard rectangular waveguide (TE₁₀ mode) and 50 Ω coaxial interface (TEM mode). Widely used in radar, satellite communications, test and measurement, RF frontends and antenna systems, they serve as a critical bridge connecting waveguide devices and coaxial equipment.
