RF2323 Preliminary 4 3V GENERAL PURPOSE AMPLIFIER Typical Applications • Broadband Gain Blocks • Driver Stage for Power Amplifiers • Low Noise Amplifiers • Oscillator Loop Amplifiers • IF or RF Buffer Amplifiers • Receiver Front-Ends Product Description 4 Optimum Technology Matching® Applied ü Si BJT GaAs HBT GaAs MESFET Si Bi-CMOS SiGe HBT Si CMOS 0.15 0.05 GENERAL PURPOSE AMPLIFIERS The RF2323 is a general purpose, low-cost silicon amplifier designed for operation from a 3V supply. The circuit configuration with resistive feedback allows for broadband cascadable amplification. Capacitive compensation extends the bandwidth of the amplifier and input stage design optimizes noise figure. The device is unconditionally stable and internally matched to 50Ω. The only external components required for specified performance are bypass and DC blocking capacitors (as shown in application schematic). The RF2323 is available in a very small industry-standard SOT-23 5-lead surface mount package, enabling compact designs which conserve board space. 1.60 + 0.01 0.400 1 2.90 + 0.10 0.950 2.80 + 0.20 3° MAX 0° MIN 1.44 1.04 Dimensions in mm. 0.127 0.45 + 0.10 Package Style: SOT 5-Lead Features • DC to >2000MHz Operation • 2.7V to 3.3V Single Supply • 2.3dB Noise Figure • 21dB Gain at 900MHz • 12dB Gain at 1900MHz GND 1 5 RF OUT • High Isolation (33dB at 900MHz) GND 2 RF IN 3 4 VCC Ordering Information RF2323 RF2323 PCBA Functional Block Diagram Rev A4 010720 3V General Purpose Amplifier Fully Assembled Evaluation Board RF Micro Devices, Inc. 7628 Thorndike Road Greensboro, NC 27409, USA Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com 4-107 RF2323 Preliminary Absolute Maximum Ratings Parameter Supply Voltage Operating Ambient Temperature Storage Temperature Rating Unit 4.0 -40 to +85 -40 to +150 V °C °C Caution!
