| Abstract: | An LNA module overlapping GPS L1 frequency band and COMPASS B1 frequency band is designed and implemented. LNAs of the module are realized by discrete components. The matching circuits can be debugged flexibly to meet the high requirements of input and output VSWR of the module. Test results show that the LNA module gain is 26 dB with high flatness, an input and output VSWR 〈 1.5, a noise figure 〈 2 dB, an out-of-band suppression of 80 dBc, and an output 1 dB compression point of 8 dBm, which meet the demand of receiver front end of navigation system. |
