Full text: PDF


Equivalent gain amplification and broadband networks matching of weak microwave signal are difficult in Ultra-wideband microwave receiver system. A highly integrated amplifier IC ADL5541 from ADI is adopted as the core unit in this paper, coordinate with an external matching network. The design can realize an Ultra-wideband microwave amplifier with 15dB gain which works in the 500~4000MHz with +25dBm of high input linearity magnification. S-parameter curves of the amplifier are simulated by calling the S2P file of ADL5541 in Agilent's ADS simulation software, and then the key parameters of external circuits are determined. The experiments show this kind of design can meet the general applications of microwave receiver systems by measurement under the condition of frequency range 500 ~ 2000MHz.
