We report the design and demonstration of wideband, high-dynamic-range integrated circuits ICs for 1-20GHz and1-40GHz dual-conversion receivers. The ICs upconvert from 2-22GHz to a 94GHz first intermediate frequency IF,and then downcovert to a second IF or to baseband. For a 0.5-22GHz input, the upconversion ICs have 19-29dBm IIP3,and 9dB insertion loss and noise figure. If preceded by a low noise amplifier with 12dB gain and 2dB noise figure, the receiver would have 6.7dB noise figure and 11dBm IIP3. Spurious local oscillator LO harmonic responses are high due to an easily-rectified design error without this, the receiver LO spurious responses would have been c.a. -40 to 45dBc.
