%X <p>A 3-5 GHz ultra-wideband (UWB) low noise amplifier based on common source (CS) with inductive-source and quarter-wave impedance convertor was proposed. The quarter-wavelength impedance convertor provides wideband input matching without noise figure (NF) degradation. The proposed UWB low noise amplifier was verified and implemented with packaged GaAs PHEMT device for 3.1-5 GHz UWB system. The measurement demonstrates a 12&plusmn;1.5 dB in-band gain, a minimum NF of 1.8 dB. Good input and output matching are obtained.</p>
