A 2.5 GHz BiCMOS differential LNA for WLAN front-end receiver is presented. The LNA is fabricated with a JAZZ 0.35 µm 1P4M SiGe BiCMOS process. The LNA provides a 50Ω input impedance and achieves good temperature characteristic. In the point of 2.5 GHz, the LNA exhibits a maximum small signal voltage gain of 29.1 dB, noise figure of 1.316dB, input/output return loss better than 11 dB, and input IIP3 of −0.241 dBm, respectively. The LNA consumes 3.7 mA of current from a 3.0V DC supply.
