Coaxial Connectors (RF)

RF Coaxial Connectors are key components for RF/microwave signal transmission. They use coaxial structures to achieve efficient electrical connection and separation between devices or within systems. Its core function is to ensure the stability of high-frequency signal transmission while reducing signal loss and electromagnetic interference.

1. Coaxial Connectors (RF) Overview

‌Basic Structure‌: It consists of an inner conductor (transmission signal), an outer conductor (shielding layer), an insulating medium (electrical isolation), and a shell (mechanical protection);

‌Impedance Matching‌: It is usually designed to be 50Ω (communication equipment) or 75Ω (video equipment) to reduce signal reflection;

‌Coaxial Advantages‌: The coaxial design of the cylindrical inner and outer conductors effectively suppresses electromagnetic leakage and external interference.

2. Development History of Coaxial Connectors (RF)

Origin: The first UHF connector was born in 1930, suitable for low-frequency signal transmission;

Military Promotion: During World War II, radar and communication needs gave rise to medium-sized series such as N, BNC, and TNC;

Miniaturization and Standardization:

After 1958, miniaturized products such as SMA and SMB appeared; the MIL-C-39012 standard was formulated in 1964 to promote the global standardization process;

Modern Development: Gradually formed an independent professional system and evolved towards high frequency and high reliability.
