Ultra wideband systems find applications in indoor and high speed applications. Being baseband transmission, it exhibits properties like low power and low cost design. Especially, IR-UWB systems demonstrate such characteristics. The performance of IRUWB system is mainly dependent on LNA design. In this paper, the authors have designed three LNA's, a wide band and two low band. A SIMULINK based transmitter and receiver model is designed based on BPSK to evaluate the performance. The wide band LNA is phase linear and one low band LNA is noise cancellation type. Both LNA designs are tested on Agilent's ADS software for 25 micron technology.
