SA631

NOTES:
1. Transients exceeding 8V on V_CC pin may damage product.
2. Maximum dissipation is determined by the operating ambient temperature and the thermal resistance, JA: 20-Pin SSOP = 110°C/W
3. Pins 19 and 20 are ESD sensitive (mixer outputs).

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 of SA631 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 of SA631 can be powered down to further reduce the supply current to less than 20A.
