Place and connect all the parts as shown in the above figure. Note that for this part you will use the standard BJT model with the "Ideal Forward Beta (BF)" parameter. You need the standard model to perform a DC operating point analysis. R3, R4, R5 and R6 are DC bias resistors. The resistors R3 and R4 acts as a voltage divider for the power supply VCC. R5 and R6 control and determine the collector and emitter currents, respectively. L1 and L2 are tuning inductors and C1 and C2 are tuning capacitors. The RF chokes L3, L4 and L5 pass the DC currents but block the AC signal and effectively remove the resistors R3, R4 and R5 from the RF analysis. The bypass capacitor C3 shorts the resistor R4 in the AC analysis. The DC blocking capacitor C4 isolates the DC bias circuitry form the load but acts as a short circuit for AC analysis. Note that for this circuit, the tuning capacitor C2 also acts as a DC blocking capacitor which isolates the bias circuitry from the AC source.
