Abstract
A low noise amplifier (LNA) system having a constant noise factor (Const-NF) mode and a constant third-order intercept (Const-IP3) mode is disclosed. The LNA system includes an LNA core and a trade-off bias network coupled to the LNA core to selectably bias the LNA core to realize the Const-NF mode and the Const-IP3 mode. The trade-off bias network is made up of selectable Const-NF circuitry and selectable Const-IP3 circuitry. The LNA system further includes a bias switching controller that is configured to enable the selectable Const-NF circuitry and disable the selectable Const-IP3 circuitry to select the Const-NF mode in response to a first condition and to disable the selectable Const-NF circuitry and enable the selectable Const-IP3 circuitry to select the Const-IP3 mode in response to a second condition.
