TNC Coaxial Connectors
The Amphenol TNC connectors are made to a high quality level. Medium size coaxial connectors
with thread coupling. 50 ohm impedance for applications up to 11 GHz and 75 ohm impedance up
to 1 GHz. Cable entires full crimp or clamp type with soldered or crimp center contact.
75 Ohm Series
Within the internationally standardized TNC mating face dimensions, a perfect 75 ohm characte-
ristic impedance cannot be realized. However, at frequencies up to 1 GHz, the small impedance
deviation is negligible for practical applications. A typical SWR of 1.15:1 at 1 GHz is achieved.
All 75 ohm TNC connectors and 50 ohm TNC connectors are intermateable.
