Es Wr62 H

What Is the ES WR62 H Adapter?

The ES WR62 H is a compact waveguide‑to‑coaxial transition designed for high‑frequency applications ranging from 12.4 GHz to 18 GHz. It converts the rectangular WR62 waveguide interface into a 2.92 mm (K‑type) coaxial connector, allowing seamless integration of waveguide components with modern vector network analyzers, signal generators, and antenna test setups.

Key Features and Benefits

• Frequency range: 12.4 GHz – 18 GHz (covers X‑band and part of Ku‑band).
• Low VSWR: Typically better than 1.2:1 across the band, ensuring minimal signal reflection.
• Compact design: End‑launch flange saves space in crowded test rigs.
• Precision machining: Gold‑plated interior surfaces reduce loss and improve repeatability.
• Durable construction: Brass body with stainless‑steel flanges withstands repeated mating cycles.

Typical Applications

The ES WR62 H adapter is widely used in the following scenarios:

1. Microwave test equipment: Connect a nanoVNA or a laboratory VNA to waveguide components without needing a bulky waveguide test set.
2. Radar system development: Provide a reliable link between waveguide feed horns and coaxial measurement gear.
3. Antenna characterization: Measure gain and pattern of X‑band antennas in an anechoic chamber.
4. Satellite communication research: Support Ku‑band transceiver prototypes that still rely on waveguide interconnects.

Choosing the Right ES WR62 H Adapter

When selecting a waveguide‑to‑coaxial adapter, consider the following factors to ensure optimal performance:

• Connector compatibility: Verify that your test instrument uses a K‑type connector; otherwise, a compatible adapter (e.g.,
