Freescale Semiconductor Data Sheet: Advance Information Document Number: MC13852 Rev. 2.0, 12/2010 MC13852 Package Information Plastic Package: MLPD-8 2.0 x 2.0 x 0.6 mm Case: 2128-01 MC13852 General Purpose Low Noise Amplifier with Bypass Switch 1 Introduction The MC13852 is a cost-effective high gain LNA with low noise figure. This is the lower application frequency version of the MC13851. 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. The external resistor used to set device current enables balancing required linearity with low current consumption. Gain is optimized for applications 1000 MHz. Gain: 20.3 dB (typ) at 434 MHz, 18.7 dB (typ) at 900 MHz. Output third order intercept point (OIP3): 10.6 dBm at 434 MHz, 14.2 dBm (typ) dBm at 900 MHz. Noise Figure (NF): 1.65 dB (typ) at 434 MHz, 1.2 dB at 900 MHz. Output 1 dB compression point (P1dB): 7.8 dBm (typ) at 434 MHz, 9.6 dBm (typ) at 900 MHz. IP3 Boost Circuitry. Bypass mode return losses are comparable to active mode, for use in systems with filters and duplexers. Bypass mode improves dynamic range in variable signal strength environments. Integrated logic-controlled standby mode with current drain < 1uA. Total supply current variable from 3–6 mA using an external bias resistor. Average current drain 1, MSG =|S21/S12|, if K
