Abstract :
Duplexer requires stability in terms of fast
signal switching between transmitting and receiving
channels on full duplex cellular telephone equipment. In
this experiment, The duplexer device is the Band Stop
Filter (BSF) L-shaped method with the 7th and 9th order
Butterworth response. The design begins by determining
the desired frequency limit, namely 3.7 GHz.
The experimental results show that the Butterworth
response BSF has a better level of stability and insulation
performance. In terms of order level, it has been proven
that the higher order (order 9) has a better isolation
performance value than the lower order (order 7).
