Product Description
The RF3861 is a low noise amplifier with a high output IP3. The amplifier
is self-biased from a single voltage supply with 50惟 input and output
ports. The useful frequency range is from 700MHz to 3800MHz. A 1dB
noise figure and 36dBm OIP3 performance is achieved with a 5V V
DD
,
90mA. Current can be increased to raise OIP3 while having minimal effect
on noise figure. The IC is featured in a standard QFN, 16-pin, 3mmx3mm
package.
