![]() ![]() They have limited power-handling capability.Ģ.92mm / K type connectors have similar performance to 2.4mm designs, but are limited to 40 GHz. 3.5mm connectors tend to have lower power ratings compared with SMA connectors.Ģ.4mm connectors are rated to 50 GHz and are available in three grades general-purpose, instrumentation, and metrology. They can handle power levels between BNC and TNC connectors.ģ.5mm connectors are precision designs similar to an SMA connector but with an air dielectric that supports frequencies up to 34 GHz. SMA, sub-miniature type A, connectors are rated for up to 18 GHz, with precision designs rated up to 26.5 GHz. Like BNC connectors, N connectors are available with characteristic impedances of 50 or 75 Ω. Standard versions are rated for 11 GHz, with precision designs capable of operating to 18 GHz. The threads provide a more solid connection that can withstand vibrations and handle higher frequencies and power levels than BNCs. TNC connectors are threaded versions of a BNC connector. BNC connectors are typically rated for 500V and about 100W average power up to about 1 GHz however, they are most commonly used at 500 MHz and below. (Image: A R RF/Microwave Instrumentation)Ī few of the common connector types used in RF applications include:īNC connectors are inexpensive, include a locking mechanism to prevent unintentional disconnection, and are available with characteristic impedances of 50 or 75 Ω. ![]() Figure 1: Typical power and frequency handling capabilities of representative RF connectors. A connector’s physical size, frequency range, and power handling capabilities are interrelated (Figure 1). Six keys to selecting and integrating GHz connectors include physical size, frequency range capabilities, power handling, voltage standing wave ratio (VSWR) and return loss, passive intermodulation distortion (PIM), and controlling unwanted electromagnetic interference (EMI). Designers have a broad range of connectors to choose from, but there are a few key parameters to consider when narrowing down the choices. This adapter can be used along with our line of ATC-PS precision test cables which are available in a number of pre-configured lengths.Connectors are essential components in radio frequency (RF) systems, especially in high-frequency applications like Gigahertz (GHz) 5G devices. This 50 ohm adapter operates up to an extended frequency range of DC to 22 GHz. The high-performance right-angle SMA adapter features a gold plated, brass body and gold plated, beryllium copper contact. This incorporates all of the physical advantages of standard right-angle designs (low profile, compact size, etc.) while maintaining electrical performance comparable with conventional straight connectors. The recently released high-frequency right-angle SMA adapter instead uses a two-piece concept with an internal swept right-angle configuration. While the straight configuration allows for easy assembly and low cost, it’s shape is not advantageous for internal impedance control or lend itself to a robust solder connection. This is due to the typical usage of a two-part internal straight contact. Traditional right-angle connectors are often associated with poor VSWR performance, particularly at frequencies approaching the limit of the connector. The right-angle SMA adapter is ideal for SATCOM, radar and test and measurement applications. ![]() This adapter is designed to offer improved VSWR over a right-angle soldered design with a similar footprint, without using an expensive swept body style. Amphenol RF has expanded its robust adapter portfolio with a high-performance right-angle SMA adapter.
