TEA-4214 Series Matching Transformer

TEA-4214 is a wide band matching transformer operating in two impedance configurations. The 4214 is mainly used as Line Matching and Bridging Transformer.  Windings connected in parallel for lower impedances ( 100 to 150 Ω) and connected in series for higher impedances ( 600 to 900 Ω).

Features: 
  • Very wide band
  • Low insertion loss
  • Low bridging loss
