Direct coupling type

Centre Frequency (fo) is available in

the range from 450kHz to 470kHz.

The standard tolerance of fo is

± 2kHz. For synthesizers and digital

indicators a tolerance of ± 1kHz is

available.

The LP455JL series, with its two

directly coupled elements, realizes a

high degree of selectivity. The series

features excellent matching
