1GHz low voltage LNA and mixer
Product specification
SA611
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
20µA.
FEATURES
• Low current consumption
• Outstanding gain and noise figure
• Excellent gain stability versus temperature and supply voltage
• LNA and mixer power down capability
