A new Penta-Band Low Noise Amplifier (PB-LNA) for vehicular communication applications that works simultaneously at navigational frequencies viz., 1.2 GHz, 1.5 GHz and wireless Communication frequencies viz., 2.4 GHz, 3.3 GHz and Dedicated Short Range Communication frequency (DSRC), 5.8 GHz is designed and analysed. Frequency transformation method is adopted for the input matching network of the designed PB-LNA. The output matching circuit is designed with a LC matching network by applying load-pull methodology. The LNA is unconditionally stable for the desired frequency bands. The power gain of PB-LNA is in the range of 10 dB to 12 dB. Noise figure (NF) below 2dB is achieved in the band of interest.
