T2 - IEEE microwave and wireless components letters Y1 - 2019 VL - 29 IS - 5 SP - 339 EP - 341 DO - 10.1109/LMWC.2019.2906595 UR - https://ieeexplore.ieee.org/document/8681076 AB - In this letter, a 125-143-GHz frequency-reconfigurable BiCMOS compact low-noise amplifier (LNA) is presented for the first time. It consists of two cascode stages and was fabricated using a 0.13-µm SiGe:C BiCMOS process, which integrates RF-MEMS switches. A systematic general design procedure to obtain a balanced gain and noise figure in both frequency states is proposed. The LNA size is minimized by using only one RF-MEMS switch to select the frequency band and a multimodal three-line microstrip structure in the input matching network. The measured gain and noise figure are 18.2/16.1 and 7/7.7 dB at 125/143 GHz. The power consumption is 36.8 mW. The measured results are in good agreement with simulations. AB - © 2019 IEEE.
