85,38 MHz

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

Input: Pin 10

Output: Pin 5

Input: Pins 10 and 9

Output: Pins 5 and 4

Note :

The balanced - balanced network is realized using M/A-COM 1:4 baluns TP-103. The insertion

filter insertion attenuation. S-Parameters of the M/A-COM 1:4 baluns TP-103 are available on re-

quest.

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.
