A concurrent multi-band LNA for multi-standard radios

• A source-degenerated cascade LNA, which works at 2.4GHz and 5.8GHz simultaneously, is designed for Bluetooth and IEEE wireless LAN 802.11 a/b/g receivers. In this design, 0.15 mu m GaAs PHEMT technology and embedded passives in MCM-D substrate are implemented. At 2.4GHz and 5.8GHz, this LNA provides 12.2dB and 15.3dB gain, respectively. Noise figures of the LNA are 0.53dB and 1.43dB, respectively. Good input matching and output matching are also achieved-S11 and S22 at both frequencies are less than -10dB.
