SMA terminators are compact, precision RF terminations designed for high-frequency applications up to 18 GHz or higher. With a threaded coupling mechanism and 50-ohm impedance, they ensure minimal signal reflection in test setups, communication systems, and RF circuits requiring accurate impedance matching and stable performance.

Category Insights

An SMA terminator is used to absorb signals at the end of an SMA-terminated RF line or port. This prevents reflections that could interfere with system performance. They're commonly used in lab testing, communication modules, and microwave circuits for reliable signal termination.

What is the frequency range of SMA terminators?

Most SMA terminators support frequencies from DC up to 18 GHz, with some precision models reaching even higher. Their excellent high-frequency characteristics make them ideal for modern RF and microwave systems requiring consistent signal integrity.
SMA and RP-SMA (Reverse Polarity) connectors are not directly compatible due to differences in pin and socket arrangement. Always verify connector type before use. Using mismatched connectors can lead to signal loss or damage to the device.
SMA terminators are available in a range of power ratings, from low-power versions (0.5W–2W) for general testing to higher-power models (5W or more) for more demanding applications. Always match the terminator's power rating to your system to avoid overheating or damage.
They are widely used in RF modules, wireless communication systems, lab instrumentation, and network analyzers. Their compact size and high-frequency performance make them ideal for tight spaces and applications requiring precision terminations at microwave frequencies.
