SA621 Description
The SA621 is a bined low-noise amplifier, mixer and VCO designed for high-performance low-power munication 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 pensation to vary less than ±0.2dB over -40 to +85°C temperature range.
SA621 Key Features
- Low current consumption
- Outstanding gain and noise figure
- Excellent gain stability versus temperature and supply voltage
- LNA, mixer and VCO power down capability
- Monotonic VCO frequency vs control voltage
