Product specification
SA621
DESCRIPTION
The SA621 is a combined low-noise amplifier, mixer and VCO
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 12dB noise figure and IP3 of
+4.5dBm at the input at 881MHz. The integrated VCO circuit with
external resonator produces a high quality LO signal that drives the
mixer and is buffered to an external PLL synthesizer IC. The
nominal current drawn from a single 3V supply is 13.3mA.
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, mixer and VCO power down capability
• Monotonic VCO frequency vs control voltage

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