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 SAW
except for a 15-dB gain. The THS9001 is mounted on the standard EVM with VS = 5 V, R(BIAS) = 237 â¦, and
L(COL) = 470 nH. Note the amplifier does not add artifacts to the signal.
