APPLICATION INFORMATION (continued)

Figure 24 shows the THS9001 and Sawtek #854916 SAW filter frequency response along with the frequency

response of the SAW filter alone. The SAW filter has a center frequency of 140 MHz with 10-MHz bandwidth

and 8-dB insertion loss. It can be seen that the frequency response with the THS9001 is the same as with the
