In communications systems, Low Noise Amplifiers (LNAs) amplify weak signals received by the antenna. Their applications extend from wireless infrastructure systems to satellite communications. For example, they are deployed in GPS receivers, public safety radios, base station receivers, military communications, and wireless test instruments, etc. Today’s commercial system designs in the RF/microwave industry are becoming increasingly complex. Part of this complexity is due to the constant strive for complete mobility and high data rates requiring portable devices to operate on various communication bands and standards while using the existing infrastructure. In turn, the increased complexity has pushed RF designers to demand more evolved design tools to minimize risk and improve their chance of first pass success. The issue is that a simulation can only be as accurate as the weakest model used for the simulation.
