170 MHz IF Amplifier Design
Optimizing the MGA-31189 for best IRL and good IP3 at
170 MHz closely follows the 70 MHz design procedure, but
the input and output tuning conditions must change for
a different *
Figure 15 shows the schematic diagram for a complete
170 MHz circuit, and Table 6 shows the component part
list.
