Abstract

In this paper, a compact 2.45/5.5-GHz dual-band low-noise amplifier (LNA) is proposed, which is realized through the heterogeneous integration of the 0.18- m CMOS and the integrated passive device (IPD) technologies. The proposed dualband LNA employs bridged-T coils for input and output matching network designs, such that the desired dual-band response can be easily achieved. Specifically, the measured small-signal gain is 15.6/12.1 dB at 2.45/5.5 GHz, while the measured noise figure is 2.6/2.8 dB. Good linearity is also achieved and the measured input P1dB is -18/-14 dBm at 2.45/5.5 GHz.
