Ningbo Hanson Communication Technology Co., Ltd. Home / Products / RF Coaxial Connector / 1.85mm Connector

1.85mm Connector

Description:

The 1.85mm series connector (also known as the 1.85mm RF connector) is a high-performance radio frequency (RF) connector that is primarily used in applications that require high frequency, high precision, and low loss, especially in signal transmission at 26.5 GHz or higher. It is a compact design of the SMA series connector that provides a smaller size and higher frequency performance compared to other high-frequency connectors such as the V Type (2.92mm) or K Type (1.0mm).

Parameter:

Main Technical Specifications:
◆ Characteristic Impedance: 50Ω
◆ Frequency Range: DC～67GHz
◆ Insulation Resistance: ≥3000MΩ
◆ Dielectric Withstand Voltage: 500V(rms)
◆ Voltage Standing Wave Ratio (VSWR): ≤1.30
◆ Mating Cycles: 500 times
