| Zusammenfassung: | The present invention relates to solid state, low noise cascode amplifiers, and particularly to such amplifiers having high linearity.
A cascode low noise amplifier has high linearity while maintaining desirable values of other cascode configured low noise amplifier parameters. Emitter degeneration is employed to improve IIP3 while maintaining gain through bias optimization and providing a termination for harmonics produced in the circuit, resulting in maximization of linearity and dynamic range providing good noise figure, gain, in/out isolation and return loss. |
