SIPU RF Technology supplies TNC Female Connector Flange Semi-Rigid Cable solutions precisely developed for mission-critical RF applications. The proposed SIPU-TNC-KFB2 model has an operation frequency range of DC-11GHz with 50Ω characteristic impedance and strong flange-mount construction. The assembly has VSWR ≤1.3 and insertion loss ≤0.06 √F(GHz) dB, providing excellent signal integrity. This connection assembly satisfies the stringent requirements of the aerospace, defence and telecommunications sectors with dielectric withstanding voltage of 1,500V and insulation resistance more than 5,000MΩ. The threaded TNC interface with a secure flange installation offers excellent vibration resistance and mechanical stability for high performance RF systems.
The TNC Female Connector Flange Semi-Rigid Cable is a specialised RF connector arrangement employing a threaded TNC female interface and flange-mount housing. This architecture is designed to solve major connection stability problems in high vibration and high interference settings.
Whereas bayonet-mount BNC connectors have a threaded coupling mechanism for continuous electrical contact and increased mechanical security . The flange part provides a sturdy means to connect to a chassis or bulkhead and insulates the internal solder junctions from outside mechanical stresses.
The best choice for situations requiring maximal EMI/RFI shielding and phase stability is this arrangement. This design provides solid performance when signal leakage or connection decoupling may lead to system failure.
