Tune the MAX2530 LNA for 450MHz CDMA2000 Operation - AN2869
ثبت نشده
چکیده
The MAX2530 receiver RF front-end IC, using Maxim's advanced SiGe process, was originally designed for cellular-band and PCS band operation. For 450MHz CDMA, the NF (noise figure) and the IIP3 (input third-order intercept) of the low noise amplifier (LNA) are very critical in considering the sensitivity, and the single-tone desensitization effect. This technical note gives the tuning method and measurement data for using the MAX2530 in a 450MHz cdma2000® application.

The cdma2000 system is an evolutionary enhancement of the IS-95 standards which support 3G services defined by the International Telecommunications Union (ITU). cdma2000 comes in two phases: 1XRTT and 3XRTT (1X and 3X indicates the number of 1.25 MHz wide radio carrier channels used and RTT stands for Radio Transmission Technology). The cdma2000 1XRTT, which operates within a 1.25 MHz bandwidth...
متن کاملInsights into structure, dynamics and hydration of locked nucleic acid (LNA) strand-based duplexes from molecular dynamics simulations
Locked nucleic acid (LNA) is a chemically modified nucleic acid with its sugar ring locked in an RNA-like (C3'-endo) conformation. LNAs show extraordinary thermal stabilities when hybridized with DNA, RNA or LNA itself. We performed molecular dynamics simulations on five isosequential duplexes (LNA-DNA, LNA-LNA, LNA-RNA, RNA-DNA and RNA-RNA) in order to characterize their structure, dynamics an...

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...
متن کاملEffect of dietary linolenic acid (18:3n–3)/linoleic acid (18:2n–6) ratio on growth performance, tissue fatty acid profile and histological alterations in the liver of juvenile Tor tambroides
This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar tothe diet with 0.0 LnA/LA ratio but different in total amounts of C18polyunsaturated fatty ac...
