Amphenol's APC is the first instrument-grade coaxial connector series to achieve repeatable TE11 mode resonance-free signal transmission from DC - 50 GHz with a minimum return loss of 26 dB. These 50 Ω connectors are designed primarily for use in test and measurement equipment where reliable performance is critical for repeated connect/disconnect cycles.
SMA is an acronym for SubMiniature version A and was developed in the 1960's. It uses a threaded interface. 50 Ω SMA connectors are semi-precision, subminiature units that provide excellent electrical performance from DC to 18 GHz. These high-performance connectors are compact in size and mechanically have outstanding durability.
There are two families of Type N connectors: Standard N (coaxial cable) and Corrugated N (helical and annular cable). Their primary applications are the termination of medium to miniature size coaxial cable, including RG-8, RG-58, RG-141, and RG-225. RF coaxial connectors are the most important element in the cable system. Corrugated copper coaxial cables have the potential to deliver all the performance your system requires, but they are often limited by the performance of the connectors.
There are two types of TNC connectors: Standard and Reverse Polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks. Other manufacturers may use reverse threading to accomplish reverse polarity keying.
The 1.0/2.3 series is a European design introduced in the 1990s. The compact design of the 1.0/2.3 permits dense connector packing; they are ideally suited to applications where space limitation is a factor. Versions are available with threaded coupling mechanisms which provide positive mating or a unique push-pull coupling system which allows quick installation. The Amphenol push-pull process is patented and ensures positive locking.
The SMC name derives from SubMiniature C (the third subminiature design). The SMC design was developed in the 1960's. SMC has threaded coupling with 10-32 threads, and is available in 50 & 75 Ω impedance. It utilizes die cast components on non-critical areas to provide a low cost solution.
The MMCX series is also called MicroMateTM. It is one of Amphenol's smallest RF connector lines and was developed in the 1990's. MMCX is a micro-miniature connector series with a lock-snap mechanism allowing for 360 degrees rotation enabling flexibility in PCB layouts. MMCX connectors conform to the European CECC 22000 specification.
MCX connectors conform to the European CECC 22220 spec and were introduced in the 1980's. While the MCX uses identical inner contact and insulator dimensions as the SMB, the outer diameter of the plug is .140 inches, which is 30% smaller than the SMB. This series provides designers with options where weight and physical space are limited. MCX provides broadband capability though 6 GHz with a snap-on connector design. A range of connectors are available , including printed circuit board and cable connectors.
Developed in the late 1940s as a miniature version of the Type C connector, BNC stands for Bayonet Neill Concelman and is named after Amphenol engineer Carl Concelman. The BNC product line is a miniature quick connect/disconnect RF connector. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. BNCs are ideally suited for cable termination for miniature to subminiature coaxial cable (RG-58, 59, to RG-179, RG-316, etc.)
The SMB name derives from SubMiniature B (the second subminiature design). Developed in the 1960's, the SMB is a smaller version of the SMA with snap-on coupling. Amphenol's SMB connectors conform to the requirements of MIL-C-39012, and the interface is in compliance with MIL-STD-348. Available in 50 Ω and 75 Ω impedance, the SMB provides broadband capability through 4 GHz with a snap-on connector design and utilizes die cast components on non-critical areas to provide a low-cost solution.
With the deployment of 750 MHz Hybrid Fiber Coax (HFC) networks, it became increasingly obvious that existing low performance F receptacles could not be used in high speed cable modems and customer interface units (CIUs). The industry has challenged connector manufacturers to develop high performance connectors featuring -30 dB return loss at 1 Ghz. Additionally, these high performance connectors must still accept .022-.042 in. diameter conductors. All connectors comply with a 3/8-32 thread specification. Amphenol has responded to this market demand providing high performance alternatives.
Amphenol's 81 Series FME connectors are used for mobile antenna applications and can be adapted for either UHF, Mini-UHF, TNC, BNC and N connector interfaces using BSA adapters.
Introduced in the 1970's, Mini-UHF is a miniature version of the UHF connectors that were invented in the 1930's for use in the radio industry. Mini-UHF connectors are designed for use as coaxial interconnection in cell phones, automotive systems, and similar applications where size, weight, and cost factors are critical.
The 1.6/5.6 series is a European design with two coupling versions: Threaded provides positive mating, Push - pull allows quick installation. Amphenol 1.6/5.6 coaxial connectors are miniature 75 Ω units operating from 0-1 GHz. The compact design of the 1.6/5.6 permits dense connector packing making these connectors ideally suited to applications where space limitation is a factor. This series compiles with DIN 47295, DIN 41626, DIN 47297, NFC 93-569, NFC 93-570, IEC 169-13, and the CECC 22230 standards.
Invented in the 1930's by an Amphenol engineer named E. Clark Quackenbush, UHF coaxial connectors are general purpose units developed for use in low frequency systems from 0.6 - 300 MHz. Invented for use in the radio industry, UHF is an acronym for Ultra High Frequency because at the time 300 MHz was considered high frequency. UHF connectors feature a threaded coupling. Because these connectors are low-cost, the impedance is variable.
Twinax connectors are used with 78 Ω and 95 Ω conductor cables and operates from 0-200 MHz. Due to the improved shielding characteristics (>30dB), these connectors are used in balanced low level and high sensitivity circuits. This connector meets applicable sections of MIL-C-3655. Twinax connectors feature keyway polarization to ensure system integrity and prevent signals from being mixed. Ideal for computer network applications.
Twin BNC connectors are used with 78 Ω and 95 Ω conductor cables and operates from 0-200 MHz. Due to the improved shielding characteristic (>30dB), these connectors are used in balanced low level and high sensitivity circuits. Twin BNC features the same two-stud bayonet locking mechanism as standard BNC connectors and polarized contacts (one female, one male) to prevent signals from being mixed. They are ideal for computer network and process control devices.
