Impedance Matching Transformers

JFW’s online impedance matching transformer models are listed in the table below.  An impedance matching transformer is a low loss device used to match two systems that have different impedance.  The models below are used to match a 50 Ohm system to a 75 Ohm system.  These models are bandwidth limited due to the internal reactive transformer designs.

Impedance Matching Transformer Options

• Any RF connector combination (BNC, SMA, N, TNC, 7/16, F, reverse polarity, with bead-chains and more)
• Any impedance matched (50 Ohm, 75 Ohm, 93 Ohm, 100 Ohm, 125 Ohm and many more)
• Affordable custom models available upon request
