RF OUT

Step 1: Choose V CC (1.8 V Min to 10 V Max)

Step 2: Insure that Min V ENBL is . minimum indicated in Figures 5 and 6.

Step 3: Choose bias current, I C3 , and calculate needed I out from typ H FE3

Step 4: From Figure 1, read V ref for V CC and I out calculated.

Step 5: Calculate Nominal R5 = (V CC – V ref ) –•• (I C3 + I out ). Tweak as desired.
