A Low Noise Amplifier for an Ultra Wideband Receiver

This paper presents the design and performance of the Low Noise Amplifier for a UWB Receiver. The amplifier utilizes commercially available components using a balanced microstrip structure. It provides an overall gain around 10 dB over the entire UWB band (3.1-10.6 GHz). The input and the output reflection coefficients are better than -13 and -20 dB, respectively. The noise figure of the amplifier is 3 dB over the frequency band.
