Do You Have Models For Your LNA's?
We do not have non-linear models for our LNA’s. Some of our GaAs products do have a model. They are listed here: Modelithics Qorvo GaN Library - Qorvo S-parameters are available at the product webpage at the “Documents”… |

When I Bias my GaN PA the Drain Current Increases to the Current Limit (No RF Applied)
You may be experiencing DC bias oscillation. Long test cables (i.e. test setup) may increase DC bias lead inductance making the PA unstable. Adding a large capacitance (such as 47 uF in correct polarity) across the gate … |

How Do Qorvo LNA Datasheets State Thermal Resistance?
Rth (thermal resistance) will always be junction/channel to case bottom (tbase). We do not characterize the thermal resistance to top of case as it is a much higher thermal resistance path: |
