Electrical properties

• Conservatively rated 1/1 transmission line transformer.
• Operation principle: Coaxial Common-Mode Choke.
• Very high common-mode impedance. (Substantially higher than what’s obtainable with the “beads over coax” approach).
• Max. power:
• 2400 W PeP @ VSWR < 2.0/1 (ICAS)
• 1200 W PeP @ VSWR < 2.0/1 (CCS)
• For ICAS and CCS power definitions, refer to Documentation
  
  
• Deployable frequency range: 1.5 to 30 MHz.
• Intrinsic VSWR : < 1.15 / 1 at the frequency range edges.
