Test method :

4.5.1. Insertion loss test setup :

The insertion loss of a device connected into a given transmission system is defined as the

ratio, expressed in dB, of the load power available(before and after insertion ) delivered to

the output network beyond the point of insertion at a given frequency. In general , the

insertion loss of a device inserted in a given transmission system is mainly caused by

internal component resistive loss while all of the impedance between source , load and

device interface having been matched. To perform the insertion loss measurement ,thru

calibration must be done prior the testing . General Insertion loss equation can be

expressed as following. Insertion loss = 20 log

V2 / V1 dB where

V1 = the measured voltage value of load without LPF in circuit.

V2 = the measured voltage value of load with LPF in circuit.

The test setup is shown in drawing below :

Note : Z

R = 270 ohm + ( 750 ohm // 150nf )
