820-980 MHz LOW NOISE BALANCE AMPLIFIER WA08-2433A1
WA08-2433A LNA is a super low noise
figure, wideband, and high linearity amplifier
with unconditional stable design. The amplifier
offers typical noise figure of 0.45 dB and typical
output IP3 of 38 dBm at the frequency range
from 820 MHz to 980 MHz. WA08-2433A LNA is
most suitable for cellular base stations, wireless
data communications, tower top receiver
amplifiers, cellular micro-cells, last-mile wireless
communication
systems,
and
wireless
measurement applications.
