Product Description
The RF3865 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 1dB
noise figure and 36dBm OIP3 performance is achieved with a 5V VDD,
180mA. Current can be increased to raise OIP3 while having minimal
effect on noise figure. The IC is featured in a standard QFN, 20-pin,
5mmx5mm package.
