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 matched to 50?. 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.
