This advantageously reduces or ---- eliminates performance penalties in one or more gain modes. The variable impedances can be configured to improve linearity of the GC amplification process in targeted gain modes. The variable gain amplifier can be configured to provide a low-loss bypass mode in a 1-1 © low gain mode to improve signal quality. ei C [Continued on next page] WO 2018/045024 Al MIDEDIMOMMIDIRERIONOHEINHOIDEHMEMOIMIE UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
