Note 1: Component values selected are based on the desired frequency and bias level. Values may be adjusted for a specific response.
Note 2: Two 160 Ω resistors are combined in parallel to achieve a minimum power handling requirement and an 80 Ω resistance.
Note 3: Evaluation Board does not include resistor R2. Operating at 28 V and 50 mA requires the R2 resistor with a power dissipation greater than 1.35 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.
