Product Description
The RF3863 is a low noise amplifier with a high output IP3. The amplifier
is self-biased from a single voltage supply with 50Ω input and output
ports. The useful frequency range is from 700MHz to 3800MHz. A 0.8dB
noise figure and 36dBm OIP3 performance is achieved with a 5V VDD,
90mA. Current can be increased to raise OIP3 while having minimal effect
on noise figure. The IC is featured in a standard QFN, 16-pin, 3mmx3mm
package.

R2 is DNP for standard 90 mA current draw. If
R2 is added, the IDD will increase. A 20 Ω R2
will raise the current to achieve higher linearity.
