Coaxial connectors


Coaxial connectors, also known as RF (radio frequency) connectors, are widely used components in various applications, ranging from household electronics to professional telecommunications equipment. They serve to transmit radio frequency (RF) signals, encompassing a broad bandwidth from tens of kilohertz to multiple gigahertz.

Construction and Operation:

Coaxial connectors are constructed with conductive and insulating layers arranged concentrically around a central axis. The inner conductor carries the RF signal, while the insulating layers provide separation and minimize signal attenuation. These connectors are characterized by a characteristic impedance, most commonly 50 or 75 ohms, which must be matched to the impedance of the cable and devices connected to the connector.

Types of Coaxial Connectors:

There exists a diverse range of coaxial connector types, varying in size, impedance, mounting method, and application. Some of the most popular types include:

  • BNC: A versatile connector with small dimensions, often used in household electronics like televisions and VCRs.

  • TNC: A rugged connector with higher power handling, employed in professional telecommunications equipment.

  • SMA: A miniature connector operating at high frequencies, commonly found in wireless applications.

  • N: A high-power connector utilized in radio and radar networks.

  • F: A connector widely used in television and radio antenna installations.
