APPLICATIONS INFORMATION
+ [) d& C& [4 uFigure 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 5.3 i1 V3 ]2 Z' T! n3 C
