Low noise amplifier (LNA) is usually used as the first stage of receivers and is characterized by low noise figure and high linearity. The structure is based on two matched cascades. The first one is a common-emitter bipolar transistor and the second is common-gate FET. Commutable feedback is used to improve the linearity in the lower range of operating frequencies (130...435 MHz).
The block is fabricated on iHP SiGe BiCMOS 0.25 um (SGB25V) technology.
