Abstract
A gain-controlled low noise amplifier means is provided. The amplifier means comprises an amplifier (T1), a first and second pin diode (D1, D2) coupled in series with opposite forward directions in a negative feedback loop of the amplifier (T1) between an input and an output of the amplifier (T1). The amplifier means furthermore comprises a first current source (IC1) coupled to a node between the first and second pin diode (D1, D2) and a second current source (IC2) coupled to an input of the amplifier (T1).
