DESCRIPTION
The SA611 is a combined low-noise amplifier, and mixer designed
for high-performance low-power communication systems from
800-1000MHz. The low-noise preamplifier has a 1.7dB noise figure
at 881MHz with 15dB gain and an IP3 intercept of -7dBm at the
input. The gain is stabilized by on-chip compensation to vary less
than
0.2dB over -40 to +85
C temperature range. The
wide-dynamic-range mixer has a 12dB noise figure and IP3 of
+7.0dBm at the input at 881MHz. The nominal current drawn from a
single 3V supply is 8.3mA. Additionally, the entire circuit can be
powered down to further reduce the supply current to less than
20
A.
FEATURES
Low current consumption
Outstanding gain and noise figure
Excellent gain stability versus temperature and supply voltage
LNA and mixer power down capability
