Abstract
A 5.8-GHz monolithic low-noise amplifier (LNA) with a minimum noise figure of 1.65 dB and an associated gain of 15 dB is implemented in a standard SiGe bipolar technology. It dissipates 13 mW from a 1-V supply (with only 9 mW in the gain stages). The measured transducer gain is 13 dB with a noise figure of 2.1 dB at 5.8 GHz. This is believed to be the lowest noise figure reported for a 5.8-GHz LNA in any production-level technology. The transducer gain is above 10 dB from 3.8 to 8 GHz. At 5.8 GHz, the input return loss and reverse isolation are 6 and 28 dB, respectively.Keywords
