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