Low Loss Filter for Mobile Communication

Data Sheet

Test matching networks to 50

Ω (element values depend on pcb layout)

a) Unbalanced - unbalanced matching network

b) Balanced - balanced matching network

Note :

The balanced - balanced network is realized using TOKO 1:1 baluns B5FL. The insertion attenu-

insertion attenuation.

The level of ultimate suppression may be limited by electromagnetic feedthrough depending on

the layout of the pcb and the arrangement of the matching components.

The above mentioned characteristics can be realized either in balanced or in unbalanced mode

of operation.
