MTT Innovations / RF interconnect studio
The right cable.
The right connection.
Explore cable construction, compare electrical characteristics and build a starting specification for your next RF assembly.
01 / Start with the cable
Choose what matters to your design.
Select a family or filter by frequency and size. Reference model names identify the researched cable types; MTT will confirm the final assembly code and availability.
Your comparison
02 / Define your assembly
Two ends. One considered connection.
Try cable and connector combinations, then send your requirements to MTT. This is an engineering enquiry builder, not an approved configuration or checkout.
Assembly concept / interactive 3D
Drag horizontally to rotate. Use arrow keys when focused. Connector forms and cable route are illustrative, not to scale.
03 / Know your interface
Get familiar before you connect.
Explore every connector family named in the selection guide, plus 1.0 mm and 0.8 mm from the connector catalog. A family name does not guarantee a cable termination is available.
Connector / 3D
Simplified educational geometry. Thread pitch, interface dimensions and internal contacts are not manufacturing definitions.
Male/female views explain conventional contact gender. Reverse-polarity connectors require a separate specification. For TNCA and SC, exact geometry must be confirmed from the chosen part drawing.
How connector compatibility is assessed
The 2022 selection guide supplies the cable-to-connector option matrix. A marked option means the family was listed, not that every gender, frequency or mounting style is available. Missing entries are shown as unverified rather than impossible.
SMA, 3.5 mm and 2.92 mm interfaces can be mechanically intermateable; 2.4 mm and 1.85 mm form another group. Cross-family mating requires suitable parts in good condition and does not extend the lower-rated interface's electrical performance. Never force mismatched connectors together.

04 / Practical selection notes
Understand the trade-offs.
Frequency
Check the cable and both connector ratings. The lowest relevant limit constrains the proposed assembly.
Loss
Cable attenuation increases with length. Connector and termination losses add to the cable contribution.
Movement
Flexible does not mean unlimited flex life. Specify bend radius, motion pattern, cycle count and phase stability.
Power
Power capability depends on frequency, temperature, altitude, mismatch and the weakest component. Ask for an assembly rating.
What is inside a coaxial cable?
A centre conductor carries the signal. A dielectric maintains spacing to the outer conductor or shield, which provides the return path and controls field containment. Flexible cables typically add a protective jacket; semi-rigid constructions use a formed metal outer conductor.
Impedance depends on geometry and dielectric properties. A connector that physically fits does not establish the correct impedance or RF performance.
What do the connector millimetre names mean?
Names such as 2.92 mm and 1.85 mm identify the nominal outer-conductor dimension of a precision coaxial interface. They are not the outside diameter of the connector body or the cable jacket.
What should I include in a quotation request?
Frequency band, impedance, both end interfaces and genders, length and tolerance, quantity, loss and VSWR limits, power and temperature, motion and minimum bend radius, armour, phase or delay matching, and any environmental requirements.
