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.
