Typical Applications
• Broadband Gain Blocks
• Final PA for Low-Power Applications
• IF or RF Buffer Amplifiers
Product Description
The RF2314 is a general purpose, low-cost, high perfor-
mance amplifier designed for operation from a 2.7V to 6V
supply with low current consumption. The circuit configu-
ration with resistive feedback allows for broadband cas-
cadable amplification. Feedback with capacitive
compensation extends the bandwidth of the amplifier, and
is designed for optimized noise figure. The device is
unconditionally stable and internally matched to 50Ω.
No
external components
are required. The RF2314 is avail-
able in a very small industry-standard SOT 5-lead surface
mount package, enabling compact designs which con-
serve board space.

Description
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
Same as pin 1.
RF input pin. This pin is internally DC-blocked and thus does not
require an external blocking capacitor. The input impedance of this pin
is internally matched to 50Ω using resistive feedback.
