In the paper, a broadband microwave receiver front-end covering the 0.5 to 19.5 GHz frequency band and providing a 1.1-GHz instantaneous bandwidth is described. The noise figure of the front-end is as low as 10 dB and the input third-order intercept point is up to 10 dBm as well. The front-end features a low spurious response and a low phase noise impressed. Essential design principles of the front-end are unveiled and discussed.
