Coaxial Impedance Converters: Types, Structure, and Uses Explained
What Are Coaxial Impedance Converters?
BNC and N Type Coaxial Impedance Converters.
Impedance converters enable matching between different characteristic impedances. Conversion is typically from 50 Ω to 75 Ω or 75 Ω to 50 Ω. Three methods are used for impedance conversion—transformer, resistance, and transmission circuit—each selected based on application and frequency bandwidth.
Why Is Impedance Matching Necessary?
When electronic devices are connected with mismatched impedances, signal reflection and attenuation occur, reducing communication quality and measurement accuracy. To prevent this, impedance matching is essential.
When combining devices with different impedances, such as 50 Ω and 75 Ω, an impedance converter ensures matching and maintains system stability.
What Happens if There Is an Impedance Mismatch?
- ・ Signal Reflection: Signals bounce along the transmission line, causing delivery errors.
- ・ Power Loss: Power fails to reach the intended device, reducing efficiency.
- ・ Measurement Error: Inaccurate results occur when the measurement system is not impedance-matched.
Benefits of Impedance Matching
- ・ Stable signal transmission
- ・ Prevention of device compatibility issues
- ・ Greater accuracy in measurement and communication

Main Applications of Impedance Converters
Impedance converters are used to minimize signal reflection and loss when connecting devices with different impedances. Key applications include:
･ Connection with Measuring Equipment:
Used to link equipment of different impedances, such as 50 Ω measuring instruments and 75 Ω devices under test.
･ Broadcasting and Video Equipment:
Broadcast systems commonly use 75 Ω, requiring converters when interfacing with equipment of different standards.
･ Wireless Communication Equipment:
Conversion between 50 Ω and 75 Ω is often needed in testing and connection environments for communication systems.
50Ω↔75Ω Conversion : Common Usage Scenarios
Typical usage scenarios include:
･ Connecting a network analyzer (50 Ω) to CATV equipment (75 Ω)
･ Matching a video signal transmission line (75 Ω) with measuring equipment (50 Ω)
･ Linking a professional camera (75 Ω BNC) to a modulator (50 Ω input)
In these cases, precise impedance matching is essential to prevent signal degradation and deterioration of the standing wave ratio (SWR).
