As one of the most common components used in the RF technology, Coaxial Connectors experience a wide usage in antennas, amplifiers, shielding applications. The MS-156C3(20) is a model provided by the MSD connector family, usually used for digital applications where a precision interface is required.

Application Field

The small size of MS-156C3(20) makes it ideal for use in instruments, military, antennas and small mounting footprints. Due to the high performance it offers, it is often featured in cellular devices, satellite communication systems and any application with high frequency signal transmission.

It also can be applied in automotive, broadcast equipment, consumer electronics and medical device industries. Some of its most popular applications include converting the basic signals into RF signals, minimization of tolerances and protection from oxidation.

Working Principle

MS-156C3(20) use a threaded or crimp attachment mechanism to interface the cable to the connector. The threaded, crimped sleeve the wire is then placed inside the male connector before the ferrule (a ring shaped component) is unscrewed to tighten it onto the wire.

Moreover, the male and female connectors attach to one another through miniaturized pin-and-socket connection. Specifically, the MS-156C3(20) is designed with 20 contacts on 0.05” (1.27 mm) spacing, optimized for space conservation in high density applications.

Signal Characterstics

MS-156C3(20) supports a high frequency range up to 6 GHz, with a highly consistent impedance of 50 ohm, providing a perfect radiofrequency signal transmission. Moreover, with features such as durable construction, great salt spray resistance and atmospheric corrosion resistance, the connector can handle adverse conditions for reliable performance.

Additionally, the MS-156C3(20) ensures a good VSWR for high frequency applications, and excellent return loss up to 35 dB with flexible cables or shielded cables. This also results in more amplifiers with better power transmission performance.

Overall, the MS-156C3(20) Coaxial Connectors belong to MSD series of RF connectors. It is used to transmit high-frequency signals with a maximum of 6 GHz. It is well-suited for a wide range of applications due to its small size, high performance and cost-effectiveness.
