75 ohm N Solder Plug

CANARE solder type 75 ohm N plug for L-8CHD.

Key Features and Benefits

  • Gold plating on the contact pin prevents deterioration, even after years of use
  • Return loss: 26.4 dB @ 2 GHz
  • Solder type
    Tools required: 17 mm and 21 mm wrenches
Caution:
The connecting section of the N connector uses a shape that conforms to the IEC169-16’s 75 ohm impedance standard. Note that the 50 ohm N and other connectors that do not conform to this specification cannot be connected.

Technical Note

Voltage Standing - wave Ratio (VSWR) and Return Loss

Terminating the receiving end of a limited length coaxial cable using a resistance value not equal to its characteristic impedance creates a reflected wave that returns back down the cable to the sending end. The result is interference developing between the travelling wave and the return wave which results in a standing wave that causes voltage levels to fluctuate. The degree to which terminating resistance matches the characteristic impedance is indicated using the VSWR or voltage standing-wave ratio standard shown in Fig. 1. Going hand in hand with the VSWR ratio is the return loss factor which measures the size of the reflected wave current in relation to the travelling wave current. (See Fig. 2)
