Waveguide Quick-Release Connectors
Quick-release waveguide joints and optional dust covers for repeated connection and service access. The verified QDPM table lists WR size, frequency band, maximum VSWR, insertion loss and length.
Quick-Release Waveguide Joints for Repeated Service Access
Quick-disconnect waveguide assemblies for fast attachment and removal without screw-and-nut fastening. Dolph Microwave supplies quick-release waveguide joints and optional dust covers for repeated connection and service access. The verified QDPM table below gives the exact WR size, band, maximum VSWR, insertion loss and length for each listed model. Send the mating flange and mechanical requirement for configuration review.
Match the waveguide and flange before you order
The quick-release assembly is selected around the actual waveguide size and mating flange. It removes screw-and-nut fastening from repeated connection and disconnection. A dust cover can be specified when the open interface needs protection during storage, transport or maintenance.

A clear interface description lets us check the part family before model selection.
Frequency & WR size
Operating band and waveguide designation.
Mating flange
Cover, grooved or choke flange designation.
Mechanical requirement
Length, available space, material, finish and dust-cover requirement.
Existing reference
Current model, drawing or interface photo when replacing an existing part.
For power or other mechanical constraints that affect the interface, include them with the RF path data.
Send Your RequirementFast access to the waveguide joint
Quick attachment and detachment is useful where the waveguide joint is opened repeatedly for assembly, test or maintenance. The optional dust cover protects an unused interface against dust, moisture and other environmental contaminants.
DH-100WQDA76PPA
All Dolph-MW models include a SurTec/corrosion-protection treatment and are painted flat black. Flanges are unplated, polished and SurTec-treated. Other finishes and paint colors are available upon request.
