This paper presents a study and design of tunable concurrent dual-band receiver. Different system architectures and building blocks have been compared and analyzed. A tunable concurrent dual-band receiver front end has then been fabricated and characterized. It operates across a tri-tave 6-18GHz bandwidth with a nominal 17- 25dB conversion gain, worst-case -15dBm IIP3, and worst case -24.5dBm ICP1dB.
