Abstract :
A low noise amplifier (LNA) for UHF UWB radar receiver is implemented in this paper. Based on negative feedback technology, this LNA has a gain above 32dB. The gain flatness is below 1.1 dB. With the operating current under 50mA, the noise figure is less than 1.5dB. The LNA is integrated into the UWB receiver, which can reduce the gain flatness of receiver and avoid saturation and overload of receiver.
