WR340 Waveguide Step Twist (DH-32WST90)

High-Performance S-Band 90° Polarization Rotation

Product Overview

The DH-32WST90 is a precision-engineered WR340 (R26) waveguide component optimized for the 2.20 GHz to 3.30 GHz frequency range. Utilizing a specialized multi-step internal transformer geometry, this 90° twist achieves field rotation in a compact 180mm axial length. This design is approximately 45% shorter than traditional helical twists, making it ideal for high-power radar feeds, medical LINAC systems, and SATCOM manifolds where space and signal integrity are critical.

Technical Specifications

Feature Specification
Waveguide Size WR340 (IEC R26)
Frequency Range 2.20 – 3.30 GHz
VSWR (Max) ≤ 1.10:1
Insertion Loss ≤ 0.10 dB
Axial Length 180 mm (7.08″)
Material / Finish Alum/Copper with Chromate & Epoxy Paint

Technical FAQ

Q: What is the advantage of a Step Twist over a Helical Twist?

A: Step twists use discrete internal sections to rotate the E-field, resulting in a much shorter physical length. This reduces the overall footprint of the system and provides higher mechanical rigidity, which is vital for mobile radar and airborne applications.

Q: Can these units handle high-power pressurized systems?

A: Yes. We offer pressurized versions with integrated O-ring grooves (e.g., CPR-style flanges) that can maintain up to 30 PSI. This is essential for preventing arcing in high-peak-power S-band applications.

Q: Are custom angles like 45° or 60° available?

A: Absolutely. While 90° is standard, our CNC machining capabilities allow us to manufacture custom twist angles and bespoke lengths to meet your exact phase and mechanical requirements.
