1GHz low voltage LNA, mixer and VCO
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).
