An SMA connector serves as the primary channel through which radio frequency signals can flow between the antenna and the device it is attached to. SMA antennas are a diverse group of radio frequency antennas that possess an SMA connector for attachment to a coaxial extension cable or other radio frequency hardware. Visually it is similar to the common household 75 Ohm Type F connector that screws into cable boxes, the design varies by 2mm and the two cables cannot b connected without an adapter SubMiniature Version A (SMA) is an RF coaxial connector designed for semi-precision applications. The SMA connector is one of several RF connector designs to connect coaxial cables and antennas while preserving the signal. RF coax cables cannot be stripped and soldered together without signal loss. Both connectors are insulated with polytetratluoroethylene (PTFE) dialectric.Īn antenna with an SMA connector couples to an SMA cable: RF coaxial antenna cable shielded to prevent signal degradation. The female connector has a central receptacle for the pin, also coated with nickel or gold, the threads external to the outer casing. The barrel screws on to an SMA female antenna or coax with threading spaced at 36 threads per inch.
The male connector features a central pin coated with nickel or gold. They are also cost-effective when designed in gold-plated brass, nickel-plated brass, or stainless steel. SMA connectors have a relatively durable screw coupling (good for 500 couplings at recommended torque) and are resistance to vibration. SMA antenna and coax connectors feature 50 Ohm impedance, drawing DC from 0GHz up to 18GHz. A 433MHz antenna is also likely to be an SMA antenna. These products are intended for applications where systems may be compromised due to weather or temporary submersion.SMA was the connector of choice for most applications until RP-SMA began to replace SMA in the late 1990s, as the more popular option, Therefore there are far more RP-SMA antenna options than SMA antenna options: We have many SMA to RP_SMA antenna cable and adapter options that enable you to connect an RP-SMA antenna to an SMA cable or connector.ĭata Alliance offers SMA antennas for WiFi, LTE, GSM, CDMA, Bluetooth, base stations, radio astronomy, hand-held radios or telephones, machine-to-machine communications. They join a wide portfolio of waterproof IP-rated connectors, adapters and cable assemblies available in a variety of configurations for most industry-standard and proprietary interfaces. Sealed SMA connectors are fully tested to IP67 specifications in the mated and unmated positions. This unique design feature ensures no ingress of dust or water through the mating interface between the flange and the enclosure or panel where the connector is mounted. Their ruggedized bodies are manufactured from brass with nickel plating and gold-plated contact and are designed with internal and external gaskets. All configurations feature a compact and vibration-resistant design with reliable electrical performance up to 6 GHz. The recently released IP67 SMA connectors are available in rear-mount bulkhead crimp jack configurations for RG-178 and RG-316 double braided cable types and rear-mount bulkhead solder jack configurations for 0.141 and 0.085-in. Weatherproof sealed RF interconnects are ideal for applications that may experience dust or water ingress such as industrial equipment, base stations or outdoor kiosks.
These lightweight 50 ohm connectors are engineered for flexible and semi-rigid cable types and designed to withstand harsh environments. Amphenol RF has expanded its IP-rated waterproof sealed solutions with additional IP67 SMA connector options.
