description | Methods and apparatuses for controlling gain of a single stage cascode FET amplifier are presented. According to one aspect, a series-connected resistor and capacitor is coupled to a gate of a cascode FET transistor of the amplifier, the capacitor providing a short at frequencies of operation of the amplifier. According to another aspect, values of the resistor can be used to control gain of the amplifier. According to yet another aspect, the resistor is a variable resistor whose value can be controlled/adjusted to provide different gains of the amplifier according to a linear function of the resistor value. An input matching network coupled to an input of the amplifier can be used to compensate for different noise figure degradations from different values of the resistor. |
