Can coaxial switch handle high frequency signals
High-Frequency Coaxial Switch Performance
High-Frequency Coaxial Switch Performance
Frequency Capabilities
-
Modern coaxial switches operate up to 110 GHz for RF/microwave applications
-
Low-loss materials like PTFE (Teflon) insulation minimize signal degradation
-
Gold-plated contacts reduce insertion loss and improve signal integrity
High-Frequency Challenges
-
Impedance mismatch becomes more pronounced at higher frequencies
-
Signal reflection and insertion loss increase with frequency
-
Impedance-matched designs (50Ω or 75Ω) ensure seamless signal transfer
