Note 1: Component values selected are based on the desired frequency and bias level. Values may be adjusted for a specific response.
Note 2: Evaluation Board does not include resistor R2. Operating at 28 V and 100 mA requires resistor R2 with a power dissipation greater than 2.7 W.

Notes: VS = supply voltage; VDIODE = voltage drop across the diode; VRES = voltage drop across the resistor.
R1 and R2 values are calculated by (VS –VDIODE)/I, where I is the desired bias current. The power dissipation in R1 or R2 is calculated by I x (VS – VDIODE). The resistor selected must be
safely rated with a power greater than the dissipated power.
