Notes:
1. Backside ambient operating temperature T_A = 25°C unless otherwise noted.
2. Thermal resistance (°C/Watt) at a channel temperature T (°C) can be estimated using the equation:
θ(T) ≅ 62 x [T(°C)+ 273] / [160°C + 273].
3. Derate MTTF by a factor of two for every 8°C above T_ch.

Notes:
1. Gain may be reduced by biasing for lower I_DD. Increasing I_DD will increase Gain.
2. Minimum input return may be improved by approximately 3 dB by including a small capacitive (~30 fF) stub on the
input transmission line.
3. Noise Figure may be further reduced by optimizing DC bias conditions.
