The MC13851 is a cost-effective, high IP3 low-noice amplifier (LNA) with low noise figure. This is the leadless package version of the MC13821 device. An integrated bypass switch is included to preserve high input intercept performance in variable signal strength environments and boosts dynamic range. On-chip bias circuitry offers low system cost. The input and output match are external to allow maximum design flexibility. An external resistor is used to set device current which allows balancing required linearity with low current consumption. Gain is optimized for applications >1000 MHz. The MC13851 is fabricated with Freescale's advanced RF BiCMOS process using the eSiGe:C module and is available in the 2x2 mm MLPD-8 leadless package, offering a small, low-height, easy-to-solder solution for applications with tight printed circuit board placement requirements.


Features
