A 1-2 GHz high linearity transformer-feedback power-to-current LNA
This paper demonstrates that a double-loop transformer-feedback power-to-current low noise amplifier, to be implemented in a 0.2 mu m GaAs p-HEMT IC process, is able to obtain a noise figure less than 0.8 dB, an input return loss less than -12 dB, a flat voltage-to-current signal transfer of 180 mS, and an input-referred third-order intercept point (IIP3) of 1.8 dBm over a wideband frequency range from 1 to 2 GHz at a power consumption of 210 mW.
