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
General Purpose Amplifica-
tion
increased to raise OIP3 while having minimal effect on noise figure. The IC
is featured in a standard QFN, 20-pin, 5mmx5mm package.

R2 and R3 are DNP for typical 90 mA per channel current draw. If R2 or R3 is added,
the channel IDD will increase. A 10 Ω R2 or R3 will raise the current of a channel
to achieve higher linearity.
Note 1: For low band add a series 6.8 nH inductor on RF IN, and a shunt 15 nH inductor on RF OUT.
Inductors should be placed as close as possible to the part.
Note 2: The topology of L3, L4, C5, and C6 in the mid and high bands. They must be as shown in the chart.
