Abstract [en]

This letter presents the results of a broadband intermediate frequency (IF) section radio frequency integrated circuit designed for a W-band heterodyne radiometer receiver in a 0.13 mu m SiGe BiC-MOS process. The differential IF section which consists of an amplifier and a power detector uses inductive and resistive matching to obtain a wideband response. The IF amplifier has a measured gain of 10.0-19.5 dB at 2-37 GHz, noise figure of 6-8 dB at 1-26 GHz, and OIP3 of 7-17 dBm at 1-40 GHz. The detector has a measured responsivity of 1 kV/W and an estimated noise equivalent power (NEP) of 4-6 pW/Hz(1/2) at 535 GHz, respectively. For the IF section, the input return loss is better than 10 dB at 7-40 GHz and the responsivity is 10-82 kV/W at 5-35 GHz. The broadband properties over significantly wider bandwidths than earlier reported silicon-based IF amplifier and power detector circuits make the SiGe 5-35 GHz IF section suitable for W-band direct-conversion radiometer receiver Radio Frequency Integrated Circuits with a larger predetection bandwidth and improved sensitivity.
