Product Description
The RF3867 is a dual-channel version of the RF3863 with a low noise
amplifier and 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, 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.
