How much is the RF connector

Time:2019-04-04

RF connectors are connectors for electrical connections for signal transmission in RF applications. These connectors are used in a variety of applications from 0 to 18 GHz and above. All types of RF connectors have a male connector and a female connector. Male connectors are commonly referred to as plugs and female connectors are referred to as jacks. The center pin and the external grounding with locking mechanism provide a secure and reliable connection.

Better models can also minimize variations in the impedance of the transmission line at the connection. Mechanically, they can provide fastening mechanisms (threads, bayonet, brackets, blind fittings) and springs for low ohmic electrical contact while retaining the gold surface, allowing for very high mating cycles and reduced insertion forces. Research activities in the field of radio frequency (RF) circuit design soared in the 2000s, directly responding to the huge market demand for inexpensive, high data rate wireless transceivers.

A coaxial RF connector (RF connector) is an electrical connector designed to operate at radio frequencies in the megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding provided by the coaxial design.

The choice of RF connector depends on the frequency range, performance, size and shape of each connector type, such as SMA, N, IPEX, MCX, SMB, SMP, DIN, TNC, MMCX connector type, etc. to SMA Connector as an example:

The SMA connector is one of the most suitable RF connectors in UHF and is the majority of the SHF series. The small size and reliable performance make SMA connectors the first choice for RF engineers.

In terms of impedance matching, the SMA connector is one of the best performing connectors. The most common type is a 3.5 mm connector.

Applications: GSM, CDMA, radio communication boards, RF power amplifiers, RF isolators, power splitters, directional couplers, Wi-Fi antennas and low power UHF communication systems.


Twinlink Communication Technology (Shenzhen) Co., Ltd has more than ten years of research and development team, industry-leading three professional laboratories of machinery, electrical and environment, and an integrated industrial chain from machining, assembly testing and electroplating. A reliable choice of RF connectors.
