Abstract:	摘要： A broadband GaAs bidirectional distributed amplifier (BDA) designed using <inline-formula> <tex-math notation="LaTeX">G_{m}</tex-math></inline-formula>-bandwidth (<inline-formula> <tex-math notation="LaTeX">G_{m}</tex-math></inline-formula>-BW) extension technique is presented in this letter. A <inline-formula> <tex-math notation="LaTeX">G_{m}</tex-math></inline-formula>-BW extension configuration is investigated, and utilized in the gain stage of the BDA for enhancing gain and bandwidth performance. The isolation between forward path and reverse path is improved by using adaptive load network. The BDA exhibits small-signal gains of higher than 14.4 dB with a 3 dB bandwidth from 1.6 to 23.6 GHz. The measured output 1 dB gain compression point <inline-formula> <tex-math notation="LaTeX">(\mathrm{OP}_{1\ \mathrm{dB}})</tex-math></inline-formula> and output third-order intercept point <inline-formula> <tex-math notation="LaTeX">(\mathrm{OIP}_{3})</tex-math></inline-formula> over 3 dB bandwidth are higher than <inline-formula> <tex-math notation="LaTeX">-</tex-math></inline-formula>7 and 1 dBm, respectively. 其他題名： LMWC 出版者： IEEE 出版日期： 2016-06 出處： IEEE microwave and wireless components letters, 2016-06, Vol.26 (6), p.449-451 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1531-1309 識別號： EISSN: 1558-1764 識別號： DOI: 10.1109/LMWC.2016.2562104 識別號： CODEN: IMWCBJ
