A Highly Compact SiGe HBT Differential LNA for 3.1-10.6 GHz Ultra-Wideband Applications
A fully differential low noise amplifier (LNA) using SiGe HBT technology for ultra-wide band applications is presented. Measured results show the maximum power gain of 19.9 dB with a variation of 1.8 dB within the entire band, the noise figure is between 2.1 dB and 2.9 dB in the FCC-allocated UWB band from 3.1-10.6 GHz. The input 1-dB compression point is -17.5dBm measured at 7 GHz. All measured results show excellent agreement with the simulated ones. The total current consumption is 22mA from a 3.5V supply. The inductor-less design occupies a chip size of only 0.14mm2 including bond pads.
