摘要

设计了一种工作在13/24/35 GHz左右的新型并发三频带LNA (TBLNA)，采用新型三频带负载实现稳定和高阻带抑制。三带负载由两个带反馈的无源LC陷波滤波器组成。采用0.18 μm SiGe BiCMOS工艺制备的TBLNA在13.5/24.5/34.5 GHz时的功率增益分别为22.3/24.6/22.2 dB。各通频带的最佳噪声系数为3.7/3.3/4.3 dB, IIP3为-17.5/-18.5/-15.6 dBm。TBLNA在1.8 V电源下功耗36mw，尺寸为920 μm × 500 μm。

A 13/24/35-GHz concurrent tri-band LNA with feedback notches

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-μm 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 μm × 500 μm.
