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

µA.
