Abstract

We propose a broadband low noise amplifier with high linearity performance. The amplifier achieves broadband, low noise performance and high linearity using a bias circuit with high impedance. The bias circuit consists of an inductor, a resistor, and a current source. The circuit obtains high impedance using a high resistive component. From 0.8 to 5 GHz, the low noise amplifier shows an S21 of 20±1 dB and an S11 of less than -9 dB. The noise figure is 1.5-2.7 dB for frequencies from 0.5 to 5 GHz. The output 1-dB compression point at 2 GHz is +6.3 dBm.
