SAW Components

B4864

183,60 MHz

Low Loss Filter for Mobile Communication

Data Sheet

Recommended pin configurations / test matching networks:

a) single-ended 50

Ω / single-ended 50Ω

b) single-ended 50

Ω / balanced 50Ω

Input : Pin 10

Output : Pin 5

Input : Pin 10

Output : Pins 5 and 4

Note :

The balanced network is realized using TOKO 1:1 balun B5FL. The insertion attenuation of a

balun is 0.3 dB at 183.6 MHz. The loss of the balun is not included in the specified filter 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.
