TGA8622-SCC
6V
RF connections: Bond using two 1.0-mil diameter, 20-mil-length gold bond wires at both RF Input and
RF Output.
Measuring IDSS: Set V-, V+, and VCTRL to 0 V. Connect VCTRL to V+. Short V- to ground.
Increase V+, VCTRL from 0 V and measure I+ maximum for V+, VCTRL </= 4 V. I+ maximum is IDSS.
Maximum gain bias (in this sequence):
Set V- to -1 V, V+ to 6 V, and VCTRL to 1.5 V. Adjust V- to achieve I+ = 50% IDSS.
Gain reduction: Set bias for maximum gain condition and decrease VCTRL from 1.5 V.
(I+ will drop accordingly; do not re-adjust V-.)
