Coax Connectors

What is an RF Connector?

An RF connector (Radio Frequency connector, also called a coaxial connector) is designed to maintain the shielding of coaxial cables. It provides a secure connection and supports multiple mating cycles, with various fastening options available.

Types of RF Connectors

Common Connectors: SMA, SMB, MCX, MMCX, BNC, TNC, N, F, UHF, CRC9, TS9

Genders: Male (plug) and female (jack)

How to Choose an RF Connector?

Impedance Matching: The connector must match the system and coaxial cable impedance (50Ω or 75Ω). Mismatched impedance reduces performance.

Voltage Rating: Ensure the working voltage stays below the connector’s maximum tolerance.

Application Needs: Consider frequency range, durability, and environmental factors.

What is an RF Adapter?

A passive coaxial component that transfers signals between different connector types.

Uses

•
Gender Change: Male-to-female or female-to-male conversion
•
Connector Conversion: SMA to BNC, etc.
•
Signal Protection: Prevents wear in test setups
•
Impedance Matching: 50Ω (telecom) or 75Ω (video/CATV)

Common Types

SMA
SMB
MCX
MMCX
BNC
TNC
N-Type
UHF
F-Type

Selection Tips

Impedance: Match 50Ω/75Ω to avoid signal loss
Connector Type: Ensure compatibility (e.g., SMA male to BNC female)
Polarity: Standard or reverse options
Application: Consider frequency, durability, and environment

Common Configurations

Male-to-Female

Female-to-Female

Male-to-Male

Reverse Polarity (RP)

What is an RF Cable Used For?

RF (Radio Frequency) cables are a type of coaxial cable designed to transmit high-frequency signals. Common applications include:

TV & Broadcast Signals (Cable TV, Satellite TV)
Internet & Telecom (RF signals in networking)
Radio & Wireless Communication (Antennas, transmitters, receivers)
Medical & Military Equipment (High-frequency signal transfer)

Types of Coaxial Cables

The four main types of coaxial cables are:

Hard Line Coaxial Cable – Thick, rigid, used in high-power transmission (e.g., broadcast towers).
Flexible Coaxial Cable – Bendable, common in home TV/internet (e.g., RG-6, RG-58).
Semi-Rigid Coaxial Cable – Holds shape when bent, used in precision RF applications.
Formable Coaxial Cable – Flexible but can be shaped (used in custom installations).
