• IF or RF Buffer Amplifiers
• Driver Stage for Power Amplifiers
• Oscillator Loop Amplifiers
Product Description
The RF2325 is a general purpose, low-cost silicon ampli-
fier designed for operation from a 3V supply. The Darling-
ton 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 perfor-
mance are bypass and DC blocking capacitors and two
bias elements (as shown in application schematic). The
RF2325 is available in a very small industry-standard
SOT-23 5-lead surface mount package, enabling compact
designs which conserve board space.
