dc.description.abstract | A fully integrated SiGe BiCMOS concurrent multiband receiver front-end and its building blocks including multiband low-noise amplifiers (LNAs), single-to-differential amplifiers and mixer are presented for various Ku-/K-/Ka-band applications. The proposed concurrent multiband receiver building blocks and receiver front-end achieve the best stopband rejection performances as compared to the existing multiband LNAs and receivers.
First, a novel feedback tri-band load composed of two inductor feedback notch filters is proposed to overcome the low Q-factor of integrated passive inductors, and hence it provides superior stopband rejection ratio (SRR). A new 13.5/24/35-GHz concurrent tri-band LNA implementing the feedback tri-band load is presented. The developed tri-band LNA is the first concurrent tri-band LNA operating up to millimeter-wave region.
By expanding the operating principle of the feedback tri-band load, a 21.5/36.5-GHz concurrent dual-band LNA with an inductor feedback dual-band load and another 23/36-GHz concurrent dual-band LNA with a new transformer feedback dual-band load are also presented. The latter provides more degrees of freedom for the creation of the stopband and passbands as compared to the former.
A 22/36-GHz concurrent dual-band single-to-differential LNA employing a novel single-to-differential transformer feedback dual-band load is presented. The developed LNA is the first true concurrent dual-band single-to-differential amplifier. A novel 24.5/36.5 GHz concurrent dual-band merged single-to-differential LNA and mixer implementing the proposed single-to-differential transformer feedback dual-band load is also presented. With a 21-GHz LO signal, the down-converted dual IF bands are located at 3.5/15.5 GHz for two passband signals at 24.5/36.5 GHz, respectively. The proposed merged LNA and mixer is the first fully integrated concurrent dual-band mixer operating up to millimeter-wave frequencies without using any switching mechanism.
Finally, a 24.5/36.5-GHz concurrent dual-band receiver front-end is proposed. It consists of the developed concurrent dual-band LNA using the single-to-single transformer feedback dual-band load and the developed concurrent dual-band merged LNA and mixer employing the single-to-differential transformer feedback dual-band load. The developed concurrent dual-band receiver front-end achieves the highest gain and the best NF performances with the largest SRRs, while operating at highest frequencies up to millimeter-wave region, among the concurrent dual-band receivers reported to date. | en |
