| Abstract: | The design process of a 3cm receiving front-end is described in the paper.To miniaturize the front-end,a compact MMIC mixer chip is used in its design.The microwave office(MWO) software is adopted in the design to simulate the low noise amplifier.Either the simulating results or the experiment data show that the designed low noise amplifier is low in noise and flat in gain.And the receiving front-end is high in image rejection and good in out-of-band rejection. |
