Impedance Matching Pads
JFW’s online Impedance matching pad models are listed in the table below. An impedance matching pad is designed using internal resistors configured to properly impedance match each side to a difference impedance. The matching pad models listed below match a 50 Ohm impedance system to a 75 Ohm impedance system. Resistive matching pads are wide-band devices that operate down to DC. For 50 Ohm to 75 Ohm impedance matching, the internal resistors do create 5.7dB of attenuation loss. If your impedance matching application must have minimum loss (i.e. < 1dB), then we recommend our impedance matching transformers instead.
Impedance Matching Pad 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, 110 Ohm, 600 Ohm and many more)
- Affordable custom models available upon request
