  • Q What is the difference between SMA and MCX connector?

    A SMA connectors are utilized in wireless communication and microwave instrumentation, whereas MCX connectors are used in mobile phones and other portable electronic devices. SMA connectors are more durable and can endure high amounts of vibration, but MCX connectors are smaller and cheaper.
  • Q How long is a SMA connector?

    A Depending on the particular application and model of connector, the length of a SMA connector might change. SMA connectors are often rather small, and their length is typically measured in millimeters. A standard SMA connector has a length around of 12~14 mm. Nevertheless, depending on their design and the particular purpose they are used for, certain SMA connections may be shorter or longer.
  • Q Do I need SMA or RP-SMA?

    The particular application you're using will determine whether you require SMA or RP-SMA connections.
    Microwave applications frequently employ SMA connectors (SubMiniature version A), a type of RF connector. They generally operate at frequencies up to 18 GHz and include a distinctive screw-type connection mechanism. Devices like wireless routers, cell phones, and other items that employ radio frequency technology frequently use SMA connections. An alternative to SMA connections are RP-SMA connectors (Reverse Polarity SMA).
  • Q Are all SMA connectors the same size?

    A SMA connectors come in different sizes and their size is determined by various factors such as orientation, termination type, cable type, and panel mounting. The orientation of the connector, whether straight, right-angle, or 45-degree angle, can affect the size. The termination type, such as cable clamp, cable crimp, cable solder, PCB end launch, PCB surface mount, or PCB through hole, also affects the size. The type of cable used, whether thin or thick, also affects the size. Lastly, the panel mounting, such as 2-hole flange, 4-hole flange, bulkhead for front mount, or bulkhead for rear mount, also affects the size.
  • Q Can you extend SMA cable?

    A SMA cable may be extended using a SMA extension cable or a SMA adapter. SMA extension cables typically have the same connectors on both ends as standard SMA cables, allowing you to connect the cable to a device and then extend it to a distant location using a SMA in series adapter. For instance, if you have a 1 meter cable and need to extend it to 3 meters, you would need a SMA plug to plug in a 2 meter cable and a SMA jack to jack adapter to connect two cables.
  • Q What materials are the made of SMA connectors?

    A SMA connectors are typically made of a combination of different materials, to control the cost of product precisely, we choose the variety materials for SMA parts.The materials used are determined by the needs and application scenarios of the clients. Consumer clients, for example, require low-cost solutions. We can use brass solutions for the body, nut, pin, and socket, and PTFE for the insulator. For military and laboratory applications, we can utilize stainless steel body and nut, brass pin, beryllium copper socket, and PEEK insulator.
  • Q What are SMA connectors?

    A SMA connectors are a type of coaxial connector that was developed in the 1960s for use in high-frequency microwave and millimeter-wave applications. They are named for their screw-type mating mechanism, which allows for a secure connection between two SMA connectors. SMA connectors are commonly used in a wide range of applications, including telecommunications, networking, military and aerospace, medical equipment, and more.
  • Q What is the difference between SMA and SMB connector?

    A SMA connectors have a screw-on mechanism and are known for durability, the working frequency can up to 26.5GHz, while SMB connectors have a push-on mechanism and plug and pull easily,the working frequency is up to 4 GHz with extended to 10GHz.
  • Q Are all SMA connectors 50 ohms?

    According to IEC60169-15 standard, The SMA connectors are designed for 50 ohms systems. SMA connectors are typically used in RF and microwave applications, and a 50 ohms impedance is the standard for these types of systems because 50 ohms balance the best power handling and signal loss. The SMA Connector widely assembly with RG series, LMR series 50 ohms coaxial cables.
    Type N, BNC, TNC,MCX,F Connectors have 75 ohms version which usually utilized for broadcast industry.

  • Q What's 2.92mm Connector

    A 2.92mm (K) Connectors are RF/Microwave coaxial connectors with a mode-free operating range of 40 GHz. SMA and 3.5mm connectors are compatible with these connectors. Mario Maury first created the 2.92mm connectors in 1974, and Wiltron reintroduced them in 1984 as the K connector. These connectors are IEC 61169-35 specified and are perfect for high-frequency module and T&M applications. The 2.92mm Series c has a frequency range of 40 GHz.
  • Q What's 3.5MM Connector

    A The 3.5 mm connector is a heavy-duty coaxial connector that can operate at up to 34 GHz without mode switching. The air dielectric filled interface of this pin and socket type connector features a 3.5 mm outside conductor diameter. This connector interface works with SMA and 2.92mm connectors and can withstand several mating cycles without causing harm. Hewlett Packard invented the 3.5 mm connector in the mid-1970s, and Amphenol later marketed it as APC3.5.
  • Q What's MMCX connector

    A MMCX connectors are coaxial RF connectors that are similar to MCX but are smaller. They comply with the European CECC 22000 standard. MMCX connectors have a 500-cycle pairing rating. The connectors normally include a lock-snap mechanism that allows 360-degree rotation and a 50 ohm impedance. They can operate in a wide range of frequencies, from DC to 6 GHz. MMCX connectors can be found on Wi-Fi PCMCIA cards as antenna connectors, as well as connectors for external GPS antennas on tiny devices such as PDAs or GPS receivers, and on mobile phones to connect external GSM antennas. Different brands of in-ear monitors utilize them to connect the wire to the separate earpieces. This enables the cables to be switched or replaced. In the 1990s, they were created.
  • Q What's N Connector

    The N-type connector is an RF coaxial connector with outstanding performance. The N-type RF connector is utilized in a variety of applications, especially when RF performance is critical.
    The N-type connector is particularly useful where large voltages and great performance are required, yet it is not generally utilized in small laboratories and hobbyist applications. The N-type connector is more suitable to use with bigger low loss cables since it is physically larger than other types of connectors such as the BNC connector.
  • Q What's SMA Connector

    A SMA connectors are semi-precision coaxial RF connectors with a screw-type coupling mechanism that were created in the 1960s as a minimum connector interface for coaxial cable. The impedance of the connector is 50. SMA was initially intended for usage from DC (0 Hz) to 12 GHz, but it has now been expanded to include variations for 18 GHz and 26.5 GHz. Microwave systems, hand-held radio and mobile telephone antennas, and, more recently, WiFi antenna systems all employ the SMA connector.
  • Q What's RF Connector?

    A coaxial RF connector (radio frequency connector) is an electrical connector that operates at multi-megahertz radio frequencies. RF connectors are frequently used with coaxial cables and are meant to keep the coaxial design's shielding. The change in transmission line impedance at the junction is also minimized with better models. They provide a fastening mechanism (thread, bayonet, bracing, blind mate) and springs for a low ohmic electric contact while sparing the gold surface, allowing for extremely high mating cycles and lowering insertion force.
