Eval board material - 31mil thick FR4 with 1/2 Ounce Cu on
both sides
D.C. Blocking capacitors are ATC series 600S. A tantalum 1.0µF is used at the drain terminal. All
other capacitors are 0603 and 0805 standard chip capacitors. A 0603 size 20 Ohm Chip resistor from
Vishay is used on the gate D.C. bias line for stability.
