1. Recommended to bias each amplifier stage separately using a gate voltage range, starting from -2.5 to -0.3V to achieve typical current levels.
2. Rth is mounting dependent. Measured result when used with Excelics recommended evaluation board.

Notes:
1) External bypass capacitors should be placed as close to the package as possible.
2) Dual biasing sequence required:
a. Turn-on Sequence: Apply Vg1 = -2.5V, Vg2 = -2.5V, followed by Vd1 = Vd2 = 7V, lastly increase
Vg1 & Vg2 in sequence until required Id1 and Id2 is obtained.
b. Turn-off Sequence: Turn off Vd1 & Vd2, followed by Vg1 & Vg2
3) Demonstration board available upon request.
