Typical Applications (continued)

10.2.2 Driving Circuit Design: Input Frequencies Between 100 MHz to 230 MHz

Figure 199. Driving Circuit for Mid-Range Input Frequencies (100 MHz < fIN < 230 MHz)

10.2.2.1 Design Requirements

See the Design Requirements section for further details.

10.2.2.2 Detailed Design Procedure

When input frequencies are between 100 MHz to 230 MHz, an R-LC-R circuit may be used to optimize

performance, as shown in Figure 199.

10.2.2.3 Application Curve

Figure 200 shows the performance obtained by using the circuit shown in Figure 199.

SFDR = 86 dBc, SNR = 71.7 dBFS, SINAD = 71.6 dBFS,

THD = 93 dBc, HD2 = 86 dBc, HD3 = 99 dBc
