Coaxial Terminators Guide: Types, Structure, and Uses Explained
What are Coaxial Terminators?
A coaxial terminator is connected to open equipment to prevent reflections and turn high-frequency energy into heat. It contains an internal termination resistor and is also known as a non-reflective terminator, termination resistor, dummy load, etc.
When choosing a terminator, consider the type of connector on the equipment (plug or jack), the frequency band, and the power (wattage) it needs to handle. For high-power applications, terminators may need heat sinks to manage higher temperatures.

SMA, SMB Coaxial Terminators
SMA terminators (MIL-C-39012, IEC 60169-15) offer high performance with a secure threaded connection for microwave uses. SMB terminators (MIL-C-39012, JIS C 5415) provide a compact, snap-on solution for internal RF circuitry.
SMP, TNC Coaxial Terminators
Coaxial Terminator Specifications
Impedance
Typically 50Ω or 75Ω. Matching system impedance is essential to prevent signal reflection.
Frequency Range
Defines the operating frequency range. Precision terminators are required for high-frequency applications.
Power Rating
Indicates the maximum power the terminator can safely dissipate.
VSWR / Return Loss
Represents impedance matching performance. Better values reduce signal reflection.
Connector Type
Specifies the interface type such as SMA, BNC, or N.
Typical Applications of Coaxial Terminators
Coaxial terminators are used to absorb RF signals at the end of transmission lines and prevent signal reflection.
They are essential for maintaining signal integrity and protecting RF equipment in various systems.
Typical applications include:
Terminating unused RF ports
RF test and measurement environments
System calibration and signal integrity testing
Antenna and communication systems
How to Choose Coaxial Terminators
Selecting the right coaxial terminator requires understanding your system requirements, including impedance, frequency range, and power level. Proper selection ensures stable performance and prevents signal reflection or equipment damage.
1. Confirm Impedance
Ensure the terminator matches your system impedance (50Ω or 75Ω).
2. Check Frequency Range
Select a terminator suitable for your operating frequency.
3. Consider Power Rating
Ensure the terminator can safely handle the input power.
4. Select Connector Type
Choose a connector compatible with your system (SMA, BNC, N, etc.).
