A 13/24/35-GHz concurrent tri-band LNA with feedback notches Conference Paper uri icon

abstract

  • A new concurrent tri-band LNA (TBLNA) operating around 13/24/35 GHz has been designed using a novel tri-band load for stable and high stop-band rejection. The tri-band load is composed of two passive LC notch filters with feedback. The TBLNA fabricated on a 0.18-m SiGe BiCMOS process achieves power gain of 22.3/24.6/22.2 dB at 13.5/24.5/34.5 GHz, respectively. It has the best noise figure of 3.7/3.3/4.3 dB and the IIP3 of -17.5/-18.5/-15.6 dBm, at each pass-band, respectively. The TBLNA consumes 36 mW from a 1.8 V supply, and occupies 920 m 500 m. 2013 IEEE.
