Quick Disconnect Assembly

Dolph Microwave Double-Ridged Waveguide Quick Disconnect Assembly ensures seamless RF connectivity across 0.84–40 GHz with industry-leading VSWR ≤1.2:1, minimizing signal loss in critical systems. Featuring tool-free thumb-screw installation, it eliminates alignment errors to prevent signal leakage and impedance mismatch.Ideal for telecommunications, radar, and aerospace applications, it complies with RoHS/REACH standards and includes Surtec corrosion-resistant finishes.

Product Overview​​

Dolph Microwave’s Double-Ridged Waveguide Quick Disconnect Assembly is engineered for seamless, high-performance connectivity in demanding RF and microwave systems. Designed to operate across frequency ranges from 0.84 GHz to 40 GHz (model-dependent), these assemblies ensure minimal signal loss with a voltage standing wave ratio (VSWR) of ≤1.2:1, optimizing signal integrity in critical applications. Constructed from precision-machined aluminum or copper, the quick-release mechanism eliminates traditional screw alignment, reducing installation time by up to 70% while preventing leakage and impedance mismatch. Ideal for rapid deployment in telecommunications, radar, and aerospace systems, the assembly is compliant with RoHS and REACH standards.

​​Key Features​​

The Double-Ridged Quick Disconnect Assembly integrates a thumb-screw clamping system for tool-free installation, enabling secure waveguide flange mating in seconds. Its broad compatibility spans waveguide sizes from WRD840 to WRD180, with optional dust covers providing IP-rated protection against environmental contaminants. The use of aerospace-grade aluminum or high-conductivity copper ensures durability in harsh conditions, while chromate conversion or specialized paint finishes enhance corrosion resistance. Flange options include flat cover (FP series) and grooved (FM series) designs, supporting flexible integration into existing waveguide infrastructures.

​​Applications​​

These assemblies are indispensable in telecommunications for rapid infrastructure upgrades, radar systems requiring field-replaceable components, and satellite ground stations where precision and environmental resilience are critical. Research laboratories leverage their quick-disconnect functionality for modular experimental setups, while aerospace and defense sectors rely on their robust performance in extreme temperatures and vibration-prone environments.

Additional Notes​​

Custom finishes, colors, and flange configurations are available upon request. Each assembly undergoes rigorous testing to ensure signal integrity and mechanical reliability, with optional dust covers (sold separately) providing added protection in outdoor or high-particulate environments.
