Waveguide To Coaxial Adapter

Double-ridged waveguide-to-coaxial adapters connect WRD assemblies to coaxial instruments or RF modules. WCA right-angle and WECA end-launch models cover individual bands within 0.84–40 GHz. Match the WRD size, flange and N, SMA or 2.92 mm interface; connector and power ratings vary by model.

Waveguide–Coaxial Interface

Select the Launch Geometry, Connector and Flange

Dolph Microwave double-ridged waveguide-to-coaxial adapters connect coaxial instruments or RF modules to a WRD transmission path. WCA right-angle and WECA end-launch versions provide different cable exit directions. Match the operating band, WRD aperture, flange and connector interface before checking the installation envelope.
WCA

Right-Angle Adapter

The coaxial connector exits at a right angle to the waveguide axis. Use this arrangement where side access is required or axial clearance is limited.
WECA

End-Launch Adapter

The coaxial connector aligns with the end-launch geometry. Confirm the available axial envelope, cable bend clearance and connector access.

Interface Review

Three Interfaces Must Be Defined Together

Select the waveguide end from the double-ridged waveguide range, then specify the coaxial end and installation envelope. Frequency overlap alone does not establish flange compatibility. Confirm the power limit of the complete connected path, including the mating cable and connector.
01 / WAVEGUIDE

WRD and Flange

Select the WRD family plus cover or grooved flange designation.
02 / COAXIAL

Connector Interface

Specify connector series, male or female interface and cable or mating-part constraints.
03 / ENVELOPE

Launch Direction

Choose WCA or WECA and confirm connector clearance, overall length and flange clocking.

Applications

Typical Adapter Uses

RF Test Interfaces

Connect coaxial instrumentation to a double-ridged waveguide test setup. Define the measurement reference plane and account for the adapter when calibrating; see RF test interface selection.

Radar Subsystems

Transition between coaxial modules and broadband waveguide assemblies.

Antenna Feed Networks

Provide a controlled interface between coaxial equipment and feed components.

System Integration

Resolve mechanical routing constraints with right-angle or end-launch geometry.

Specification-Based Quotation

Submit the WRD Family, Launch Geometry and Connector Interface

Include the operating band, WCA or WECA layout, connector gender, flange designation, quantity and acceptance requirements.
