Product Description
The RF2323 is a general purpose, low-cost silicon ampli-
fier designed for operation from a 3V supply. The circuit
configuration with resistive feedback allows for broad-
band cascadable amplification. Capacitive compensation
extends the bandwidth of the amplifier and input stage
design optimizes noise figure. The device is uncondition-
ally stable and internally matched to 50Ω. The only exter-
nal components required for specified performance are
bypass and DC blocking capacitors (as shown in applica-
tion 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.
