Note:
The LM-NP/-LP-1000 Series Line
Matching Transformers meet the return
loss specifications of BS 6305.
It is important, however, to use the circuit
recommended by BS 6305 for return loss
measurements.
The LM-NP-1000 Series are EN 41003
approved.

* Due to the unique design and the most advanced manufacturing techniques the 2 coils are fully identical, meaning there is no real
primary nor secondary winding. Depending on the application, the transformers can be used either way.
