A DC-13GHz LNA for UWB RFID applications

• In this paper, we present a 4-stage traveling wave lownoise amplifier for UWB RFID (ultra-wideband radiofrequency identification). This LNA covers a frequencyrange of DC - 13 CHz. The circuit is implemented with0.I5pm 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 thegain is less than 3dB, its noise figure is less than 4dB, SI 1and S22 are around -10 dB.
