Abstract :
In this paper, the design on an MMIC broadband low-noise amplifier was briefly described in terms of SiGe process technology, circuit structure and parameter optimization, package parasitic effect and external circuit effect. After the LNA was processed, the tested results showed the following. The bandwidth of amplifier was 3.37GHz, the power gain (S21) was 29dB, the reverse isolation (S12) was less than or equal to -39dB, the noise figure (NF) was less than or equal to 2.35dB. When the signal frequency was 1.5GHz, P1dB was 9.2dBm, and OIP3 reached 21.8dBm
