50 Ohm RF Coaxial Adapters
A 50 Ohm coaxial adapter joins compatible coaxial connector interfaces without changing the signal frequency. Dolph lists same-series and between-series configurations; select the connector pair, gender, maximum operating frequency, body style and mounting from the applicable part-number row.
Match both connector ends before selecting the adapter.
Dolph Microwave lists same-series and between-series 50 Ohm coaxial adapters for connecting coaxial cables, instruments and RF components. An adapter changes the mechanical interface; it does not convert frequency or automatically match a 75 Ohm system to 50 Ohm. Select both connector ends, then check the frequency limit and body style of that part number.

Connector 1
Series and gender for the first RF interface.
Connector 2
Series and gender for the second RF interface.
Operating band
Minimum and maximum frequency required by the assembly.
Mechanical style
Straight or right angle; free-hanging or bulkhead where listed.
Do not apply the highest listed frequency to every connector pair.
The official list assigns a separate maximum frequency to each part number. Send the complete interface requirement for the correct row.

The Dolph list contains the part-number, connector, gender, conversion type, maximum frequency, style, impedance, mounting and construction fields used for selection.
Open Official PDFHow to use the published data
Use price and stock columns only as a published reference. Current price, availability and specification must be reconfirmed before order release.
A short interface check prevents the wrong adapter.
For an instrument connection, specify the required connector pair and whether the adapter remains inside the calibrated measurement path. Mechanical fit alone does not establish acceptable return loss, power handling or measurement uncertainty; request these limits for the selected part when the application requires them.
RFQ checklist
- Connector series and gender at both ends
- Required operating frequency range
- Straight/right-angle and mounting requirement
- Quantity and required documentation
Continue with the matching component family
Use when the RF path must continue at a reduced signal level.
Use when the RF path needs a matched load.
Use when the transmission medium changes between waveguide and coaxial.
Ready for a model check?
Send both connector series and genders, operating band, mounting style and quantity. Include average/peak RF power and a return-loss or insertion-loss requirement when these control acceptance.
