SA631
DESCRIPTION
The SA631 is a combined low-noise BiCMOS 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 10dB noise figure and IP3 of +3.3dBm at the input at 881MHz. The nominal current drawn from a single 3V supply is 8.3mA.
