Abstract:	A highly linear P attenuator system using a wideband IM3 cancellation technique is presented that provides 4 discrete attenuation levels with 6dB spacing for DC-5GHz. For the whole band, S11<-14dB, attenuation flatness<1.6dB, +10dBm input P1dB and +26dBm IIP3 are achieved. For the TV band (0.1Gz-1.2GHz) +30dBm IIP3 is achieved. The active area is 0.0054mm2 in a standard 0.16um bulk CMOS process.
