Antenna Low Noise Amplifier for GNSS

Popis výsledku v původním jazyce

A wideband low noise amplifier (LNA) was developed to receive signals of all the fundamental satellite navigation systems (GPS, GLONASS, Galileo, and COMPASS). The low noise pHEMT ATF-54143 from Avago Technologies with excellent noise characteristics was used as the basic building block. The amplifier is designed to be placed very close to the receiving antenna, and there are two SMA connectors used for the connection. The input one is used to connect the receiving antenna to be further connected with the amplifier through a coaxial cable which is as short as possible in order to emphasize its excellent noise characteristics. The second one serves as an output of the amplified signal and an input of DC voltage. The intrinsic amplifier is based on the substrate Isola 410, used for high frequency circuits. The entire amplifier is constructed of SMD components which comprise, besides the transistor itself, the matching and power supply circuits. A sophisticated method of the amplifier design was suggested based on multiobjective optimization. A substantial original improvement of the standard optimization method was used to satisfy a uniform coverage of Pareto front. The suggested modified algorithm for the multiobjective optimization as well as extraordinary precise circuit modeling methodology were published in the paper “Precise Characterization and Multiobjective Optimization of Low Noise Amplifiers” in the Radioengineering journal with the WoS IF=0.653. After the complex circuit design, the s21 parameter ranged from of 15 to 25 dB, and the s11 and s22 parameters were lesser than -10 dB in the range of 0.5 GHz to 3.2 GHz. The noise figure was lesser than 1dB in the range from 0.8 to 2.9 GHz, and it was near 0.5 dB at the frequencies where the main satellite navigation systems work. The measured third-order intercept point was 27.5 dBm after the multiobjective optimization. Finally, the stability of the amplifier was carefully checked.
