Broadband 0.3-7 GHz MESFET amplifier with low noise figure up to fT/2 of the active device Open
A broadband amplifier has been designed with a low noise figure up to 7 GHz using a standard 0.8 µm GaAs MESFET process (fT = 13 GHz). An active match common gate input stage, a common source output stage and a combination of resistive and…
