RF2326 Preliminary 4 3V GENERAL PURPOSE AMPLIFIER Typical Applications • Broadband Gain Blocks • Driver Stage for Power Amplifiers • Final PA for Low-Power Applications • Oscillator Loop Amplifiers • IF or RF Buffer Amplifiers Product Description 4 0.15 0.05 GENERAL PURPOSE AMPLIFIERS The RF2326 is a general purpose, low-cost silicon amplifier designed for operation from a 3V supply. The Darlington circuit configuration with resistive feedback allows for broadband cascadable amplification. The device is unconditionally stable and internally matched to 50Ω. The only external components required for specified performance are bypass and DC blocking capacitors and two bias elements (as shown in application schematic). The RF2326 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 Optimum Technology Matching® Applied ü Si BJT GaAs HBT GaAs MESFET Si Bi-CMOS SiGe HBT Si CMOS Package Style: SOT 5-Lead Features • DC to >2000MHz Operation • 2.7V to 3.3V Single Supply • +18dBm Output IP3 • 12dB Gain at 900MHz GND 1 5 RF OUT • Internally 50 Ω Matched Input and Output GND 2 RF IN 3 • 10dB Gain at 1900MHz 4 GND Ordering Information RF2326 RF2326 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 4-129 RF2326 Preliminary Absolute Maximum Ratings Parameter Supply Voltage Operating Ambient Temperature Storage Temperature Parameter GENERAL PURPOSE AMPLIFIERS 4 Min.

Keep traces physically short and connect immediately to ground plane for best performance. Same as pin 1. RF input pin. This pin is not externally DC blocked and thus requires an external blocking capacitor suitable for the frequency of operation. The input impedance of this pin is internally matched to 50Ω using resistive feedback. RF OUT RF IN 4 5 GND RF OUT GENERAL PURPOSE AMPLIFIERS 4 Same as pin 1. RF output and bias pin. The input impedance of this pin is internally matched to 50Ω using resistive feedback. Bias should be supplied to this pin through an external series resistor and RF choke inductor. Because DC biasing is present on this pin, a DC blocking capacitor should be used in most applications (see application schematic). The supply side of the bias network should be well-bypassed.
