The amplifier is self-biased from a single voltage supply with 50 Ω input and output ports. The useful frequency range is from 700MHz to 3800MHz. A 1d B noise figure and 36d Bm OIP3 performance is achieved with a 5V VDD, 180m A. 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.
