Shunt Configuration (looking into RF+ when RF- is grounded) will have higher total capacitance at RF+ due to parallel combination of Cs with parasitic capacitance CP1 (CS + CP1), as demonstrated in Figure 14 and Table 9.

The complete RF circuit must be simulated using actual input power and load conditions to ensure neither VP nor VM exceeds 30 Vpk. Figure 13. Effective Capacitance Diagram Figure 14. Typical Capacitance vs. State S11 and S21 for series configuration is illustrated in Figures 15 and 16. S21 includes mismatch and dissipative losses and is not indicative of tuning network loss. Equivalent Circuit Model can be used for simulation of tuning network loss. Table 9. Effective Capacitance Summary |
