RF2451 Datasheet | RF Micro Devices

Description .006 .002 The RF2451 is a general purpose, low-cost, high performance low noise amplifier designed for operation from a 2.7V to 4V supply with low current consumption. The attenuation of the device is controlled when in power down mode, providing a known gain step. The RF2451 is available in a small industry-standard MSOP-8 surface mount package, enabling pact designs which conserve board space. The design features accurate PTAT (Proportional To Absolute Temperature) biasing scheme using band gap cells. .196 .190 .016 .010 .120 .116 .026 .120 .116 .036 .032 10°MAX 0°MIN .027 .017 .009 .005 Optimum Technology Matching® Applied N P ro E du W ct Package Style: MSOP-8 !Si Bi-CMOS Si BJT Ga As HBT Si Ge HBT Ga As MESFET Si CMOS Features - 700MHz to 2000MHz Operation - 2.7V to 3.6V Single Supply - +5d Bm Input IP3 at 3.0m A - 12d B Gain at 1950MHz - 1.8d B Noise Figure at 1950MHz - 17d B Gain Step FO ad R e RF OUT 1 ISET 2 VCC 3 N S ee O T U pg r Bias Circuits 5 IPSET ENABLE 4 d 8 RF IN 7 GND1 6 GND2 Ordering Information RF2451 RF2451 PCBA 3V Low Noise Amplifier Fully Assembled Evaluation Board Functional Block Diagram RF Micro Devices, Inc. 7625 Thorndike Road Greensboro, NC 27409,...
