Product specification  
Low voltage LNA, mixer and VCO — 1GHz  
SA620  
DESCRIPTION  
FEATURES  
PIN CONFIGURATION  
The SA620 is a combined RF amplifier, VCO  
with tracking bandpass filter and mixer  
designed for high-performance low-power  
communication systems from 800-1200MHz.  
The low-noise preamplifier has a 1.6dB noise  
figure at 900MHz with 11.5dB gain and an  
IP3 intercept of -3dBm 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 an 9dB noise figure and IP3 of  
–6dBm at the input at 900MHz. An external  
LO can be used in place of the internal VCO  
for improved mixer input IP3 and a 3mA  
reduction in current. The chip incorporates a  
through-mode option so the RF amplifier can  
be disabled and replaced by an attenuator

APPLICATIONS  
the overall dynamic range of the receiver  
when in an overload situation. The nominal  
current drawn from a single 3V supply is  
10.4mA and 7.2mA in the thru-mode.  
Additionally, the VCO and Mixer can be  
powered down to further reduce the supply  
current to 1.2mA.
