Abstract :
In this paper, we present a 4-stage traveling wave low noise amplifier for UWB RFID (ultra-wideband radio frequency identification). This LNA covers a frequency range of DC - 13 CHz. The circuit is implemented with 0.15μm GaAs PHEMT chips embedded in flexible LCP (liquid crystal polymer) substrate. In the frequency range, the gain of the LNA is better than IO dB, fluctuation of the gain is less than 3dB, its noise figure is less than 4dB, S11 and S22 are around -10 dB.
