  • WHAT DOES LOW PIM REALLY MEAN?

    Low PIM is the buzzword of the week in wireless infrastructure as the industry decides on the new “standard” RF connector. PIM stands for Passive Intermodulation (which is similar but not the same as IMD – that is for active components) and is measured in dB’s. PIM is defined as the unwanted signal or signals generated by the non-linear mixing of 2 or more frequencies, but what does it really mean to the consumer? High PIM means poor cellular reception and limited bandwidth to the end user, which in turn means lost customers to the carrier. Low PIM means strong signals with more bandwidth for more users, which means happy customers and higher revenues for the carrier. From a hardware perspective, it means that each and every connection must be designed to minimize PIM and tested to ensure it is installed properly. That is where Amphenol is the expert.

    “Amphenol has been testing and optimizing PIM in our connectors for almost two decades.”

    Current Hardware

    The current standard wireless RF connector – 7/16 connectors – are large and heavy. They have been in the field for years, are proven to be reliable, and have good PIM performance. However, in the age of smartphones, increased data usage equates to increased RF connector density, and the 2”x 2” flange required to mount a 7/16 is too large.

    7/16 Connector 7/16 Connector

    The current alternative – N type connectors – are smaller and fit on a 1”x 1” flange, but cannot match the torque spec or PIM performance of the 7/16 connector.

    N-Type Connector N-Type Connector
    Connection Evolution

    The front runners for the crown are the 4.1/9.5 and the 4.3/10 connector. The 4.1/9.5 connector is an old interface and is commercially available, but has not achieved widespread adoption. For a list of available current generation Low PIM adapters follow the hyperlink. The 4.3/10 is a new interface based on a new specification, with nearly no time in the field. Let’s compare the two technically first, then understand the industry forces acting on the choice of next gen connectors:

    • Both meet or exceed the performance of the 7/16, but fit on a 1” flange
    • Both can handle higher torque loads than N type, reducing install failures
    • 4.1/9.5 PIM performance varies when loose or under strain (similar to 7/16)
    • 4.3/10 has the unique ability to have stable PIM while connector is loose or under strain – this increases reliability and allows it to be hand tightened
    • 4.3/10 has separate mechanical and electrical planes for optimized PIM
    4-1-9-5-Low-PIM 4.1/9.5 Bulkhead Flange Adapter

    Industry forces:

    • A major US carrier is pushing all large RF interfaces to 4.1/9.5
    • European standard is likely to be 4.3/10
    • Many carriers have not adopted 4.1/9.5, seemingly waiting for the 4.3/10

    While Verizon is supporting 4.1/9.5 at the moment, the industry at large seems to be holding off as the 4.3/10 is a strong contender for the crown of “Standard Low PIM” connector. Very likely both standards will exist and create their own niche, as is seen with the current gen products. Amphenol continues to broaden its industry leading product portfolio, offering the 4.1/9.5 in multiple configurations, and developing the 4.3/10 product line. Please contact us to learn more.

  • AMPHENOL RF BECOMES THE NEW STANDARD IN ULTRA-MINIATURE RF CONNECTORS

    Amphenol RF AMMC and AMC coaxial interfaces offer maximum performance in space saving, micro-miniature designs.

    Danbury, CT Amphenol RF introduces its ultra-miniature AMMC printed circuit board connector ideal for space-constrained RF applications with 50 Ohm impedance requirements. These connectors are fully compatible with the Hirose W.FL and IPEX MHF III series.

    Amphenol Micro Miniature Coaxial (AMMC) connectors are low profile (1.4 mm off the board, mated) with an extremely small footprint (2 mm x 2 mm). Packaged in 3,000 piece reels, these connectors feature high frequency broadband performance up to 6GHz and easy snap on/off mating. The AMMC connectors are designed to be surface mounted, which allows for higher PC board densities.

    In addition to AMMC PCB connectors, Amphenol RF offers a full AMMC product portfolio which includes AMMC cable jumpers and AMMC to SMA coaxial adapters. The jumpers offer an AMMC right angle plug to AMMC right angle plug on industry standard black 0.81 mm and 1.13 mm micro-coaxial cable.

    Furthermore, Amphenol RF has extended the AMC product line to include AMC jumpers with 0.81mm micro-coaxial cable and RG-178 cable configurations. Similar to the AMMC, The AMC (Amphenol Micro Coaxial) connector series is a low profile (2.5 mm of the board, mated) series with an extremely small board footprint (3mm x 3mm).

    The light weight, compact designs make AMMC and AMC interconnects optimal for Wireless, WLAN, Bluetooth, and GPS applications. They meet the high frequency transmission requirements of mobile phones, notebook computers, and tablets. Due to their ability to maintain superior signal integrity, AMMC and AMC connectors are also popularly used for antenna connections and cellular communications.

  • IP ratings in RF connector applications

    Most engineers (including this author) have at one time or another been accused of over-designing or over-engineering a product.  It is often claimed that tolerances that are unnecessarily tight, or a requirement is impossible to meet, or an electrical spec can't be met.  Whether its the manufacturing engineer, the purchasing manager, or a supplier, someone will be sure to give you an earful about how you don't need something that performs that well.  One such topic that runs across my desk fairly often is the IP rating of connectors.

    Lets start with some definitions!  Since ratings less than IP54 become meaningless in the connector world, lets start there and work our way up the most common ratings.  IP67 and IP68 are the two most common seen in the marketplace.  IP ratings are split between 2 numbers that reflect the products ability to resist solid particles and liquid particles.  The first number represents the solids and second number represents the liquids.

    IP54: 5 = dust protected,  4 = splash proof

    IP67: 6 = dust sealed, 7 = submersion to 1 meter for 30 minutes

    IP68: 6 = dust sealed, 8 = submersion to customer specification

    For the full breakdown please see the Connex page.

    IP_67

    The critical take-away from this brief explanation is to show that the rating can be vague, so a full understanding of the connector is critical to not over-designing your application.  In most applications when a customer purchases an IP67 connector for a non-submerged application, IP54 would achieve their goals.  If you need your panel sealed - is the connector IP67 rated to the panel or just through the interface? Is it only sealed to the panel and not through the interface?  Is it sealed in the mated condition only?  In all cases, a connector may be labeled as IP67, even though it may seem that it is a misrepresentation of the product.

    Is IP68 better than IP67?  Well, it depends - is the application fully submerged for longer than 30 minutes and at depths more than 1m?  If not, then the two ratings are largely indistinguishable.  Just because 8 is a higher number than 7, does not mean that it is "better" or more appropriate for the application.  Furthermore, IP68 is achieved to a customer specification - there is no industry standard.  Be sure to investigate the actual test (or equivalence of the test done) to determine the capabilities of the connector.  IP68 could mean that the connector is capable of 1.1m for 31 minutes or it's capable of 100m for 10 years.  Those are wildly different, but achieve the same rating.  This is a bit of trickery that marketers love to exploit.  Conversely, a well designed IP67 rated connector may meet the customer’s IP68 requirements, but because it has not been tested to that customer's specification, it has not been granted the IP68 rating.
