  • How should I interpret the impedance of an SMA connector?
    It's both the impedance of the connector alone, and the impedance of the connector plus cable, and the impedance of the connector plus cable plus another connector, and so on The characteristic impedance of a 50 Ω system is still 50 Ω no matter how many cables and connectors you put in it--as long as you terminate it appropriately
  • What are SMA connectors and what are they used for?
    SMA connectors are "rather small" when compared to BNC connectors, so I'm not sure you are seeing the type of connector you think you are seeing \$\endgroup\$ – The Photon Commented May 3, 2013 at 16:26
  • SMA connector, PCB, straight, with differential signal
    Sma is single ended connector and it is ment for single ended connections You could use it for a short, lower frequency also in a differential mode if you don't have need for a ground I would use 2x sma if possible, use the ground
  • RF - sma pth connector impedance matching to cpw
    I am designing a 4-Layer PCB with an SMT GPS GNSS receiver (1575 42 MHz), where it connects to an external antenna through an SMA Connector I have already done all the calculations of CPWG using S
  • 90 degree right angle connectors - Electrical Engineering . . .
    \$\begingroup\$ SMA connectors can have either right angle corners (formed when two pieces of wire are soldered inside the connector body) or curved swept turns \$\endgroup\$ – SteveSh Commented Jun 9, 2023 at 18:30
  • Is it possible to properly solder SMA connectors to flexible . . .
    Good quality SMA connectors are generally 'solder - crimp', you can either solder or crimp the center pin but the shield is always crimped There's really no reason to want to solder the shield, it's a pain to do, and the heat of soldering is likely to melt the insulation
  • How is the impedance of SMA (or RF) connectors measured . . .
    I am going through the datasheets of 50Ω-impedance SMA terminators, trying to understand how they measure the impedance of the connector to be 50Ω and how they show this 50Ω measurement I would expect a Smith chart in the datasheets, showing the frequency sweep and the impedance being close to 50Ω on the Smith chart from 0Hz up to the frequency the terminator is advertised as
  • impedance matching - Match SMA antenna input connector . . .
    So place your reference plane at the SMA connector and match up to that; the rest is 'assumed' to be already matched If for some strange unusual and incomprehensible reason your antenna will not be 50 ohm then you'll have to match from the coax feed to the antenna input at the attach point of the antenna
