MC13851|General Purpose LNA | NXP Semiconductors

Overview

The MC13851 is a cost-effective, high IP3 low noise 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.

Features

The MC13851 is intended for applications from 1000 to 2500 MHz and the MC13852 is for applications <1000 MHz
Gain: 18.7 dB (typ) at 1960 MHz and 17.7 dB (typ) at 2140 MHz
Output third order intercept point (OIP3): 16 dBm at 1960 MHz and 17 dBm (typ) dBm at 2140 MHz
Noise figure (NF): 1.37 dB (typ) at 1960 MHz and 1.46 dB at 2140 MHz
Output 1 dB compression point (P1dB): 8 dBm (typ) at 1960 MHz and 8 dBm (typ) at 2140 MHz
NXP^® IP3 Boost Circuitry
Bypass mode has return losses 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 < 1 µA
Total supply current variable from 2.5–5 mA using an external bias resistor.
In a receiver system with 20% active mode and 80% bypass mode the average current drain is < 0.6 mA
On-chip bias sets the bias point
Bias stabilized for device and temperature variations
MLPD-8 leadless package with low parasitics
1575, 1960, 2140 and 2400 MHz application circuit evaluation boards with characterization data are available
Available in tape and reel packaging
