| RF2314 4 Typical Applications * Broadband Gain Blocks * Final PA for Low-Power Applications * IF or RF Buffer Amplifiers * Driver Stage for Power Amplifiers * Oscillator Loop Amplifiers GENERAL PURPOSE LOW NOISE AMPLIFIER Product Description The RF2314 is a general purpose, low-cost, high performance amplifier designed for operation from a 2.7V to 6V supply with low current consumption. The circuit configuration with resistive feedback allows for broadband cascadable amplification. Feedback with capacitive compensation extends the bandwidth of the amplifier, and is designed for optimized noise figure. The device is unconditionally stable and internally matched to 50. No external components are required. The RF2314 is available in a very small industry-standard SOT 5-lead surface mount package, enabling compact designs which conserve board space. 0.400 1 2.90 + 0.10 0.950 2.80 + 0.20 3 MAX 0 MIN 0.45 + 0.10 0.127 1.44 1.04 Dimensions in mm.
