MC13851-2140EVKgeneralLow noiseamplifier, with a bypass switch
The MC13851 is a cost-effective, high IP3 low noice amplifier (LNA) with low noise figure.This is a lead-free package version of the MC13821 device.The integrated bypass switch includes high input interception performance in varying signal strength environments, improving dynamic range.On-chip bias circuitry provides low system cost.The inputs and outputs match the outside of the circuit to allow for maximum design flexibility.Using an external resistor to set the device's current balances the desired linearity with low current consumption.Gain > 1000 MHz application is optimized.The MC13851 is a fabrication of eSiGe:C modules used in Freescale's advanced RF BiCMOS process and is available in a 2×2mm MLPD-8 lead-free package, providing a small, low-height, easy-to-to-to-soldering solution for tight printed circuit boardsInstallation requirements.
