Typical Applications
• Broadband Gain Blocks
• Low Noise Amplifiers
• IF or RF Buffer Amplifiers
Product Description
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 m atched 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.
