The RF2322 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 RF2322 is available in a very small

industry-standard SOT-23 5-lead surface mount package,

enabling compact designs which conserve board space.
