The Progress Status of Broadband Precision Coaxial Connectors

The nomination method of the coaxial connectors is introduced in this paper. The structure type of the most common coaxial connectors, such as 14 mm, Type N, 7 mm, 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm and 1 mm coaxial connector,the calculation formulas of the main parameters of the coaxial connector are presented at first. And then the technology requirements of general precision connector(GPC) and laboratory precision connector(LPC) is summarized. The inner conductor pin gap, inner conductor slotted contact and inner conductor no-slotted contact are analyzed. Finally the application of precision coaxial connector is introduced in microwave instruments. The challenges that the precision coaxial connector with higher frequency and wider bandwidth will face in the furture are analyzed.
