Preliminary 4 Typical Applications GSM Handsets CDMA Handsets TDMA Handsets IF or RF Buffer Amplifiers RF2371 3V LOW NOISE AMPLIFIER Driver Stage for Power Amplifiers Oscillator Loop Amplifiers Product Description The RF2371 is a general purpose, low-cost, high performance low noise amplifier designed for operation from a 2.7V to 4V supply with low current consumption. The attenuation of the device is controlled when in power down mode, providing a known gain step. The RF2371 is available in a small industry-standard SOT23-8 surface mount package, enabling compact designs which conserve board space. The design features a highly accurate PTAT (Proportional To Absolute Temperature) biasing scheme using bandgap cells. 1.59 1.61 0.365 0.15 0.05 4 GENERAL PURPOSE AMPLIFIERS 0.127 TEXT* 2.80 3.00 0.650 2.60 3.00 *When Pin 1 is in upper left, text reads downward (as shown). 3°MAX 0°MIN 1.44 1.04 0.35 0.55 Optimum Technology Matching® Applied Package Style: SOT23-8 üSi Bi-CMOS Si BJT GaAs HBT SiGe HBT GaAs MESFET Si CMOS Features 700MHz to 2000MHz Operation 2.7V to 3.6V Single Supply +5dBm Input IP3 at 3.0mA 12dB Gain at 1950MHz 1.8dB Noise Figure at 1950MHz 17dB Gain Step RF IN 1 8 7 6 Bias Circuits 5 RF OUT ISET VCC ENABLE GND1 2 GND2 3 IPSET 4 Ordering Information RF2371 RF2371 PCBA 3V Low Noise Amplifier Fully Assembled Evaluation Board Functional Block Diagram RF Micro Devices, Inc. 7625 Thorndike Road Greensboro, NC 27409, USA Tel...
