Waveguide to Coaxial Adapters
A waveguide-to-coaxial adapter couples a waveguide mode to a coaxial transmission line at the same RF frequency. Dolph lists right-angle and end-launch versions. Select the waveguide size, flange, coaxial connector and gender, operating band, power conditions and installation orientation as one configuration.
Match the waveguide side and coax connector as one RF interface.
A waveguide-to-coaxial adapter transfers RF energy between a hollow waveguide and a coaxial line without changing the signal frequency. Dolph lists right-angle and end-launch layouts. The waveguide band, coaxial connector limit, VSWR, insertion loss and power rating must all suit the same selected model.

Waveguide side
Waveguide size, operating band and mating flange.
Coax side
Connector type, gender and impedance.
RF conditions
Frequency range plus average/peak power where applicable.
Orientation
Right-angle or end-launch and available installation envelope.
Keep family scope separate from the official model table.
The catalog overview references a wider WR2300-WR10 family, while the official model table lists WR1150-WR10 entries. Configurations outside the exact table require confirmation.

The official PDF provides model-specific frequency, WR size, VSWR, insertion loss, coax connector, power, flange, material and finish fields.
Open Official PDFHow to use the published data
Use one model row as a complete configuration. Do not combine the widest band, highest power and lowest VSWR from different rows.
Send both RF interfaces and the mechanical orientation.
For VNA testing, specify the intended reference plane. If calibration ends at the coaxial connector, the adapter contributes loss and mismatch to the measured path; use a suitable calibration or de-embedding procedure when the result must refer to the waveguide flange.

Use when both sides remain coaxial.
Use when both sides remain waveguide interfaces.
Use when the coaxial path ends in a matched load.
Ready for a model check?
Send the WR size, flange designation, coaxial connector and gender, operating band and average/peak power. Include a drawing for controlled connector orientation and identify whether the adapter is a test interface or a permanent system component.
