LM-NP/-LP 1000 Series - Line Matching Transformers
Note
The LM-NP/-LP-1000 Series Line
Matching Transformers meet the return
loss specifi cations 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.
