Applications Information
Insertion Loss
The insertion loss of the device is the ratio of the
power delivered to the load with and without the filter
in the circuit. This parameter is dependent upon the
impedance of the source and the load. The standard
impedance of test equipment that is used to measure
filter frequency response is 50Ω. In order to obtain an
accurate measurement of the filter performance, an
evaluation board with 50Ω transmission lines are
used. The test conditions for the SFC2309-200 are
shown below. The evaluation board contains SMA
connectors at each of the circuits inputs and outputs.
The connections are made with 50Ω traces. An HP
8753E network analyzer with an internal spectrum
analyzer and tracking generator is used. This equip-
ment has the capability to sweep the device from 3kHz
to 3GHz. The analyzer’s source (RS) impedance is
equal to the load (RL) impedance which is equal to
50Ω.
