INTEGRATED CIRCUITS SA631 1GHz low voltage LNA and mixer Product specification IC17 Data Handbook 1998 Jan 08 Philips Semiconductors Philips Semiconductors Product specification 1GHz low voltage LNA and mixer 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. Additionally, the entire circuit can be powered down to further reduce the supply current to less than 20µA.
