Terminations & Mismatch Loads (5 to 50 Watts)

JFW’s online 50 Ohm medium power termination and mismatch load models are listed in the table below.  JFW has been designing, manufacturing, and delivering quality terminations and mismatch loads for over 30 years.  Our mismatch loads allow you to select the impedance mismatch your RF testing requires.

Termination

The terminations listed in the model table are all 50 Ohm impedance.  Terminations are used to properly terminate a port in the matching impedance to prevent RF signal reflections.

Mismatch Load

The mismatch loads in the model table have model numbers that end with -XXX.  The -XXX is used to specify the mismatch value.  For example, JFW model #50T-034-3.0 BNC M is a  3.0:1 mismatch load (i.e. 150 Ohms) with a 50 Ohm BNC male connector.
