Measuring the SAW Bandpass Filter Using the Segment Sweep
15. Measurement Examples
1. Determine the Segment Sweep Conditions
Figure 15-1 shows the results of evaluating the transmission characteristics of the SAW
bandpass filter in the range of 440 MHz to 3 GHz by using the linear sweep.
Figure 15-1 Transmission characteristics of SAW bandpass filter (440 MHz to 3 GHz, linear
sweep)
The measurement conditions are determined for each frequency range. Here, the segment
sweep is performed following the sweep conditions shown in Table 15-2.
