240 MHz IF Amplifier Design
The 240 MHz example follows the same design approach
that was described in the previous 170 MHz design. A
schematic diagram of the complete 240 MHz circuit, with
input and output match and DC biasing components, is
shown in Figure 19. The 240 MHz component part list is
shown in Table 8.
