Keywords: LNA, impedance matching, X-band, radar.
This paper performs the study design, fabrication of a low-noise amplifier (LNA) operating at 9GHz of X-band (8GHz to 12GHz) that be able to meet requirements using for the radar’s receiver with gain greater than 10dB, noise figure less than 0,8 and reflection coefficient at the input (S11) lower than -20dB. The design circuit uses a common SPF-3043 in LNA design that is pHEMT GaAs transistor with low cost but high gain and performance, potentially extended frequency up to 10GHz
