RF2314 • Broadband Gain Blocks • Driver Stage for Power Amplifiers • Final PA for Low-Power Applications • Oscillator Loop Amplifiers • IF or RF Buffer Amplifiers 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 50Ω. No external components are required. The RF2314 is available in a very small industry-standard SOT-23 5-lead surface mount package, enabling compact designs which conserve board space. .071 .059 .004 .000 .020 .014 .122 .106 1 .083 .067 .118 .102 Si Bi-CMOS GaAs HBT GaAs MESFET SiGe HBT Si CMOS .051 .039 .010 .004 .008 MIN Si BJT GENERAL PURPOSE AMPLIFIERS 4 !" # • 150MHz to 2500MHz Operation • 2.7V to 6.0V Single Supply • +18dBm Output IP3 at 5V • 14dB Gain at 900MHz • 8.6dB Gain at 1900MHz GND 1 5 RF OUT • Low Current Consumption of 5mA at 3V GND 2 RF IN 3 4 VCC RF2314 RF2314 PCBA Rev A3 990216 General Purpose Low Noise Amplifier Fully Assembled Evaluation Board RF Micro Devices, Inc. 7625 Thorndike Road Greensboro, NC 27409, USA Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com 4-87 RF2314 Absolute Maximum Ratings Parameter Supply Voltage Supply Current Operating Ambient Temperature Storage Temperature Parameter GENERAL PURPOSE AMPLIFIERS 4 Min.
