A 1A 1.8 d13 Noise Figure Low DC Power MMIC LNA for C-Band Jakub J. Kucera and Urs Lott ETH Zurich, Laboratory for EM Fields and Microwave Electronics, Gloriastrasse 35, CH-8092 Zurich, Switzerland ; email: kucera@ifh.ee.ethz.ch ABSTRACT A two stage monolithic on chip matched low noise amplifier (LNA) for the frequency range of 5 to 6 GHz has been designed. A 50 IR noise figure of 1.8 dB and an associated gain of 16.5 dB were measured at a DC power dissipation of only 6 mW from a 1 V supply, including the bias circuitry. At 5.5 GHz the input return loss and reverse isolation are better than -10 dB and -35 dEl, respectively. stages are biased at the same current. The noise contribution of the biasing resistors are negligible. The output of each stage is loaded with a band pass LC section to……
