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.

Antenna Architecture

Four-Slot Horn Design

Design

The antenna features a four-slot horn structure that enhances impedance matching and minimizes return loss via an optimized feed design, including a tapered cavity and waveguide transition. Its arc aperture design improves high-frequency radiation patterns, addressing common issues in traditional broadband antennas. Additionally, it supports dual-polarization for versatile applications.

The four-ridge arrangement provides two orthogonal RF signal paths corresponding to horizontal and vertical linear polarization. This configuration allows polarization selection or comparative measurement without replacing the complete antenna assembly.

01

Broadband Transition

The tapered cavity and waveguide transition support broadband impedance behavior across the published operating range.

02

Dual RF Ports

Separate SMA female interfaces provide horizontal and vertical linear-polarization signal paths.

03

Aluminum Construction

Aluminum construction, conductive oxidation and anticorrosion paint support mechanical durability and surface protection.

System Integration

RF Interface and Installation Considerations

Review the full operating band, cable arrangement, mounting position and available mechanical space before integrating the antenna into a test system or platform.

HLP and VLP Configuration

The published HLP + VLP configuration provides horizontal and vertical linear polarization through separate ports. Confirm the required port assignment and measurement configuration before installation.

Two SMA Female Connectors

The antenna uses two SMA female 50Ω interfaces. Cable loss, adapter loss, connector access and cable bend radius should be included in the complete system review.

Mechanical Envelope

The published size is 140*285 mm and the net weight is 1.2 KG. Installation planning should include horn-aperture clearance, rear connector access and mounting-fixture space.

Project-Specific Requirements

Where size, weight, mounting arrangement or documentation must be adapted to a specific platform, provide the installation drawing and acceptance requirements during quotation.

Bending and twisting are different requirements

Tell us how the ends line up

Send a sketch showing the two flange faces and the route between them. Include any rotation between the faces, rather than specifying only the overall length.

Check loss at the ordered length

The model table gives insertion loss in dB/m. Compare the same waveguide size and installed length when reviewing two assemblies.

Use the rating for your size

For example, the WR650 row lists 0.12 dB/m, 10 kW average power and 5 deg/m maximum torsion. Smaller waveguides have different limits.

The flexible waveguide selection guide covers size, frequency and bend requirements. For a fixed change of direction, compare rigid waveguide bends as well.

Match the Attenuator Family to the Requirement

Use the high-power fixed matrix when the attenuation value is set and the required CW power falls within a published WHPFA model. For a different waveguide structure, power class or function, use the related family that matches the actual system.

Dolph Microwave standard fixed waveguide attenuator models in multiple rectangular waveguide sizes


Standard Rectangular Fixed Attenuation

For lower-power standard rectangular models extending to higher millimeter-wave bands, review the Waveguide Fixed Attenuator range.



Double-Ridged High-Power Attenuation

For broadband double-ridged waveguide systems, review the separate High Power Fixed Attenuator model family.



Double-Ridged Precision Fixed Models

For lower published power ratings with double-ridged bandwidth, compare the Precision Fixed Attenuator range.



Power Absorption Instead of Inline Attenuation

If the requirement is to terminate a waveguide port and absorb power, use the High Power Termination family instead of an attenuator.

Confirm Power and Flange Interfaces Before Ordering

The model number does not replace the system inputs. Average power, pulse conditions, waveguide designation and both flange interfaces should be confirmed together before the final model is released.



Power dataState average CW power. For pulsed operation, also provide peak power, pulse width and duty cycle so the requirement can be reviewed correctly.



Flange pairSpecify the exact cover or grooved flange designation required at each end. Mixed flange pairs should be stated explicitly.
