Note:
1. Gain Calculations:
( ). MAG = ^|S21| K ± K ² - 1 When K ≤ 1, MAG is undefined and MSG values are used. MSG = ^|S21| , K = ^{1 + | ∆ | 2 - |S11| 2 - |S22| 2} , ∆ = S11 S22 - S21 S12
|S12|
|S12|
2 |S12 S21|
MAG = Maximum Available Gain
MSG = Maximum Stable Gain
2. S-parameters include bond wires as follows:
GATE:
TOTAL 1 WIRE(S), 1 PER BOND PAD, 0.0134" (340 µm) LONG.
DRAIN: TOTAL 2 WIRE(S), 1 PER BOND PAD, 0.0188" (477 µm) LONG.
SOURCE: TOTAL 4 WIRE(S), 2 PER SIDE, 0.0114" (286 µm) LONG.
WIRE:
0.0007" (17.8 µm) DIA. GOLD.
