MC13853 Tri-Band Low Noise Amplifiers with Bypass Switches Technical Data
●Introduction
■The MC13853 is a SPI controlled, tri-band, high gain LNA with extremely low noise figure, designed for cellular band applications. Integrated bypass switches are included to preserve input intercept performance. The input and output match are external to allow maximum design flexibility. The MC13853 is fabricated using Freescale's advanced RF BiCMOS process using the SiGe:C option and is packaged in the QFN-16 leadless package.
●Features
■RF input frequency: 800 MHz to 2.4 GHz
■Gain: 13.5 dB (typical) at 1960 MHz, 15 dB (typical) at 2140 MHz, and 13.5 dB (typical) at 880 MHz
■Input 3rd order intercept point (IIP3): -3 dBm (typical) at 880 MHz, -4.0 dBm (typical) at 1960 MHz, and -3.0 dBm (typical) at 2140 MHz
■Noise figure (NF): 1.5 dB (typical) at 880 MHz, 1.5 dB (typical) at 1960 MHz, and 1.6 dB (typical) at 2140 MHz
■Current Settings are SPI controllable
■Freescale’s IP3 boost circuitry
■Bypass mode included for improved intercept point performance
■Total supply current:LB – 9.7 mA in current setting 6HB1 – 9.2 mA in current setting 6HB2 – 6.5 mA in current setting 210 μA (typical) in bypass mode
■Bias stabilized for device and temperature variations
■QFN-16 leadless package with low parasitics
■SiGe technology ensures lowest possible noise figure
■SPI controlled
■At POR, all bands default to bypass mode. In deep sleep mode, all bands are set to disable mode.
