摘要：

An LNA module was proposed which overlaps major bands of GNSS for the requirement of rapidly developed multimode satellite integrated navigation technology. This LNA module was integrated in a 3 mm×3 mm×1 mm plastic package by using SIP technology, which included the die of LNA, and other off-chip circuits like the input/output matching circuits. No extra element was needed outside the package. The die was fabricated using low-noise 0.25 μm GaAs pHEMT technology. A novel active bias circuit was presented in the die, which can reduce the effects of fluctuation of both the supply voltage and ambient temperature. The LNA module can stably work in complex environments. The test results showed that in the operational frequency band of the LNA module, the noise figure was about 0.65 dB, the gain reached 20 dB, the input and output return loss was less than -10 dB. IIP3 was above 0.6 dBm at the central frequency. The LNA module worked with a 3.3 V supply voltage and 15 mW power dissipation. © 2017, Zhejiang University Press. All right reserved.
