APPLICATIONS INFORMATION9 B2 ^4 S/ N/ E! u
Figure 24 shows the AD608 configured for operation in a digital system at a 10.7 MHz IF. The input and output impedance of the filter are parallel terminated using 330 Ω resistors, and the conversion gain is 24 dB. The RF port is terminated in 50 Ω; in a typical application, the input is matched to a SAW filter using the impedance data provided in Table 5.( @. U1 n6 _$ \7 k6 ~
