Influence of the Antenna Impedance Variation and Input Matching Network Q on LNA Key Figures
In this paper we present an analysis of the behaviour of a 2:4 GHz Low Noise Amplifier (LNA) for Wireless Body Area Network (WBAN) applications facing antennadetuning issue. An amplifier with ultra-low power, low voltage, and with reduced component count is prototyped to validate simulation results, then the behaviour is analyzed through simulations based on data measured on real users.
The analysis shows that the designed LNA is stable to the antenna impedance variation expectable in most cases, while highlights the possible risks associated to a high-Q input matching network when used in a context prone to antenna detuning risk.
