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.

Features

• Low current consumption
• Outstanding gain and noise figure
• Excellent gain stability versus temperature and supply voltage
• LNA and mixer power down capability
• Designed in Philips state of the art BiCMOS QUBIC process

Applications

• 900MHz cellular and cordless front-end
• Spread spectrum receivers
• RF data links
• UHF frequency conversion
• Portable radio
