The SMA connector is designed to have a constant impedance of 50 ohms on the connector. SMA connectors were originally designed and designated for work up to 18GHz, although some versions have a top frequency of 12.4GHz and some versions are designated as 24 or 26.5GHz. A higher upper frequency limit may require operation with […]

For antenna applications, ultra-small A (SMA) Connector solutions that provide bridging between RF and microwave are available for standard and reverse polarity. They are usually designed for the frequency range from DC to 18GHz, have a characteristic impedance of 50Ω, and have a threaded coupling mechanism to achieve a safe connection even in a high-vibration […]

The SMA (Sub-Miniature-A) RF coaxial connector, credited to James Cheal of Bendix Company in the United States in 1958, was born to address the TEM mode conversion challenges between coaxial and microstrip structures due to its compact size and design. This innovation brought simplicity, a wide operating frequency range, and high reliability, leading to its […]

As the trend toward connector miniaturization continues, the development of ultra-miniature connectors has gained prominence. Connector suppliers have introduced ultra-miniature coaxial connectors to meet the demands of various applications. MCX One such connector is the MCX (MicroCoaX), which originated in Europe during the 1980s. Its structure closely resembles the SMB connector, with the inner conductor […]

BNC Connectors The BNC coaxial connector, a widely used connector, was developed in the 1940s. The name “BNC” is derived from “Bayonet-Neill-Concelman,” with “Bayonet” referring to the bayonet-style connection method, and “Neill” and “Concelman” being the inventors of the N-type and C-type connectors, respectively. The BNC connector is essentially a compact version of the C-type […]

The coaxial line represents the most effective way to transmit the signal from the source to the terminal, which is embodied in the coaxial cable assembly. The distance between the source and the terminal is the length of the cable. The most important factor in choosing a radio frequency coaxial connector is the choice. Cables, […]

Classification and application of radio frequency coaxial connectors: RF coaxial connectors are divided into 4 categories according to their dimensions: standard, miniature, sub-miniature and micro-miniature. This category reflects coaxial connectors The history of development. The early coaxial cables were much larger than the commonly used coaxial cables. Therefore, the early RF coaxial connectors were very […]
