| RF Connector Type | |||
| Your choices are... | |||
| BMA | BMA connectors feature a push-on interface and a threadless outer ground connection. They can withstand both radial and axial misalignment. | ||
| BMMA | BMMA connectors are miniature BMA connectors. | ||
| BNC | Bayonet Neil-Concelman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50-ohm and 75-ohm BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors. | ||
| Type C | Type C connectors are medium-size, weatherproof devices with a two-stud bayonet coupling. They provide constant 50-ohm impedance and may be used with 75-ohm cable below 300 MHz. | ||
| Type F | Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas. | ||
| FME | FME connectors are used in mobile antenna applications. With adapters, they can also be used in place of UHF, Mini-UHF, TNC, BNC, and Type N connectors. | ||
| Type G | Type G connectors are 75-ohm impedance devices with snap-on coupling. They are well-suited for CATV applications. | ||
| MCX | Miniature coaxial (MCX) connectors provide broadband capability through 6 GHz and are used in applications where weight and physical space are limited. They provide good electrical performance and are used to address the rapid implementation of the U.S. digital cellular PCN infrastructure. MCX connectors are also used in global positioning systems (GPS) and wireless LAN (WLAN) applications. | ||
| MHV | MHV connectors are compact, high-voltage devices with 50-ohm impedance and a two-stud bayonet coupling. MHV connectors are similar in size to, but not interchangeable with, BNC connectors. | ||
| MMCX | Micro-miniature coaxial (MMCX) connectors are smaller than MCX connectors and feature a more robust interface for greater durability. They are ideal for high volume, wireless SMT or PCMCIA applications in cellular base stations, cellular phones and personal communicators. MMCX connectors are also used in global positioning systems and wireless LAN (WLAN) applications. | ||
| Type N | Type N connectors include an integrated gasket to protect against environmental ingress and create an air gap between the center and the outer conductor. They primarily have 50-ohm impedance, but 75-ohm versions for CATV, are available. | ||
| QMA | QMA connectors are quick-disconnecting devices that have the same internal construction as SMA connectors. | ||
| QWS | Quarter-wave stub (QWS) or Type Q connectors are coaxial devices with 50-ohm impedance. They are suitable for high frequency applications where characteristic impedance must be maintained. | ||

| SMC | Subminiature C (SMC) connectors are 50-ohm or 75-ohm devices with a frequency range of 7 - 10 GHz. They are smaller than SMA connectors, but can accept flexible cables with diameters as large as 3.17 mm or 0.125". | ||
| SSMA | Sub-SMA (SSMA) are miniaturized SMA connectors that are 30% smaller than standard SMA connectors. | ||
| SSMB | Sub-SMB (SSMB) are miniaturized SMB connectors that are 30% smaller than standard SMB connectors. | ||
| SMP | Subminiature P (SMP) connectors are rated to 40 GHz and, depending on detent type, can withstand from 100 to 1,000 interconnect cycles. | ||
| TNC | Threaded Neil-Concelman (TNC) connectors are similar in size to BNC connectors but feature a threaded coupling nut for applications that require performance to 11 GHz. TNC connectors are durable, reliable devices that are widely used in the cellular and mobile communication industry for equipment cabling and antenna interfaces. | ||
| Triax | Triax connectors are used with triaxial cables where maximum RF shielding and minimum noise radiation is required. | ||
| Twinax | Twinax connectors are used with twinaxial cables for balanced low level and high sensitivity circuits. Twinax connectors feature polarized key and keyway construction as well as threaded coupling. | ||
| UHF / PL259 | Ultra-high frequency (UHF) connectors are economical, all-purpose connectors designed with non-constant impedance for use in comparatively low voltage and low frequency applications such as citizens' band (CB) communications systems. UHF connectors are also used in public address systems, closed circuit television (CCTV), civil defense, landing systems, ground control apparatus, ship-to-shore communications, and mobile radio equipment hookups between antenna and transmitters or receivers. PL259 is a screw-on video connector that has been largely replaced by BNC devices. | ||
| Mini-UHF | Mini-UHF connectors are a miniature version of the original UHF connector. They feature a threaded coupling mechanism for reliable mating. Mini-UHF connectors are designed for use in cellular mobile telephone systems where size, weight and cost are critical. With crimp cable termination for low installation costs, these connectors provide excellent RF performance in applications through 2.5 GHz. | ||
| ZMA | ZMA connectors are electrically equivalent to SMA connectors. | ||
| 1.6 / 5.6 | 1.6/5.6 connectors are mechanically sturdy devices that feature a coupling mechanism. They are often used with equipment that requires resistance against environmental and mechanical stress. 1.6/5.6 connectors are also suitable for handling RF analog and digital signals in telecommunications systems. | ||
| 7-16 | 7-16 connectors are designed for use in medium to high power communication systems. These connectors perform exceptionally well in multi-channel cellular systems where power levels approximate 100 watts per channel. Designed for both flexible as well as corrugated cables, these connectors are used in a variety of cellular base station and broadcast communication applications. | ||
| 1.0 / 2.3 | 1.0/2.3 coaxial connectors are designed for telecommunications systems that require sub-miniature 50-ohm slide-on or screw-on connectors | ||

| 7 mm | 7 mm connectors are metric devices that derive their name from the inside diameter of their outer conductor. Compared to other 18 GHz connectors, 7 mm devices provide the lowest reflection coefficient and the most repeatable measurements. 7 mm connectors are also known as ACP-7, an acronym for Amphenol precision connector, 7 mm. | ||

| VSWR | In a system, impedance mismatches cause some of the transmitted energy to be reflected back to its source. The frequency of the signal determines the amount of energy that is reflected. Voltage standing wave ratio (VSWR), a unitless ratio ranging from 1 to infinity, expresses the amount of reflected energy at the input of the device. A value of 1 indicates that all the energy passes through. Any other value indicates that a portion of the energy is reflected. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
