Find the Right RF Adapter for Your Application
Selecting an RF or microwave adapter involves more than simply matching two connector types. At microwave and millimeter-wave frequencies, the adapter becomes part of the RF signal path and should be selected according to the electrical and mechanical requirements of the complete system.
Important parameters to consider include:
Connector Interface
Identify the connector required on each side of the adapter. Mini-Circuits offers adapters between identical and different interfaces, including precision microwave and millimeter-wave connector families.
Connector Gender
Adapters are available in various male-to-male, male-to-female, female-to-male and female-to-female configurations, depending on the connector family.
Operating Frequency
Always select an adapter whose specified operating frequency covers the complete frequency range of your application.
For high-frequency and millimeter-wave test applications, Mini-Circuits offers precision adapter solutions including 1.85 mm and 1.0 mm interfaces, with selected 1.0 mm models covering frequencies up to 110 GHz.
VSWR and Insertion Loss
Any additional interface in an RF signal chain can affect system performance. Review the specified VSWR and insertion-loss performance of the individual adapter, particularly in precision test and measurement applications.
Mechanical Configuration
Depending on the equipment and installation, you may require:
Always refer to the individual Mini-Circuits datasheet for the complete electrical, mechanical and environmental specifications of the selected model.
RF Adapter Connector Families
1.0 mm RF Adapters

1.85 mm RF Adapters
1.85 mm interfaces are commonly used in high-frequency test and measurement systems. Mini-Circuits offers multiple connector combinations and gender configurations for integration into RF and microwave test setups.
2.4 mm RF Adapters
Mini-Circuits 2.4 mm adapters provide solutions for precision microwave interconnections, including adapters between different high-frequency connector families.
2.92 mm RF Adapters
Choose from multiple 2.92 mm adapter configurations for RF and microwave laboratory, instrumentation and test applications.
SMA RF Adapters
SMA remains one of the most widely used RF connector families. Mini-Circuits offers multiple SMA adapter configurations for general RF and microwave interconnection requirements.
N-Type and BNC RF Adapters
N-Type and BNC adapters are available for systems using these established RF interfaces, including configurations for test equipment, communications systems and general RF installations.
Waveguide and Coaxial-to-Waveguide Solutions
For millimeter-wave applications, MCDI also offers Mini-Circuits waveguide products covering interfaces including WR10, WR12, WR15, WR19 and WR28.
Applications for RF & Microwave Adapters
RF adapters are used wherever two RF interfaces need to be connected while maintaining reliable signal transmission.
Typical applications include:
Because system requirements differ significantly according to frequency, connector interface and measurement accuracy, the specifications of the individual adapter should always be reviewed before selection.
Mini-Circuits RF and microwave adapters, available through MCDI in Israel, cover frequencies from DC up to 110 GHz, depending on the connector interface. Precision 1.0 mm adapters reach the highest end of that range, while common interfaces like SMA and N-Type typically top out between 2 GHz and 18 GHz.
The catalog includes 1.0 mm, 1.35 mm, 1.85 mm, 2.4 mm, 2.4 mm NMD, 2.92 mm, 2.92 mm NMD, 3.5 mm, BNC, N-Type, SMA, SMP, and waveguide interfaces (including WR19, WR22, and WR28), in straight, right-angle, and bulkhead/panel-mount configurations.
Selection depends on five factors: the connector interface required on each side, connector gender (male/female), the operating frequency range needed, VSWR and insertion-loss performance, and mechanical configuration (straight, right-angle, or bulkhead). The adapter’s rated frequency must cover the full range of the test setup, since it becomes part of the signal path.
Both are precision microwave connector families, but they support different maximum frequencies and are not always interchangeable without an adapter. 2.92 mm interfaces typically operate up to 40 GHz, while 2.4 mm interfaces extend to around 50 GHz; a dedicated 2.92 mm-to-2.4 mm adapter is required to mate the two families.
Yes. Coaxial-to-waveguide adapters bridge coaxial interfaces (such as 2.4 mm or 2.92 mm) to waveguide interfaces like WR19, WR22, and WR28, enabling integration between coaxial test equipment and millimeter-wave waveguide components.
VSWR (Voltage Standing Wave Ratio) measures how well an adapter’s impedance matches the rest of the RF system; a lower VSWR (closer to 1:1) means less signal reflection and better performance. Since any adapter added to a signal chain can affect VSWR and insertion loss, it’s especially important to review these specs for precision test and measurement applications.
Yes. Beyond the standard catalog, MCDI provides access to Mini-Circuits’ full portfolio of non-catalog parts and can support custom adapter designs or catalog modifications through its local Application Engineering team.
Typical applications include RF/microwave laboratories, vector network analyzer (VNA) setups, automated test equipment, 5G and wireless development, radar systems, satellite communications, aerospace and defense systems, telecommunications equipment, and production testing.
Straight adapters connect two interfaces in a direct in-line path, while right-angle adapters change the direction of the connection by 90Ā°, which is useful in space-constrained enclosures, rack setups, or where cable routing requires a bend without adding excess cable length or loss.
