LMX2216  
0.1 GHz to 2.0 GHz Low Noise Amplifier/Mixer  
for RF Personal Communications  
General Description  
The LMX2216 is a monolithic, integrated low noise amplifier  
(LNA) and mixer suitable as a first stage amplifier and down-  
converter for RF receiver applications. The wideband oper-  
ating capabilities of the LMX2216 allow it to function over  
frequencies from 0.1 GHz to 2.0 GHz. It is fabricated using  
National Semiconductor’s ABiC IV BiCMOS process.  
The LMX2216 is available in a narrow-body 16-pin surface  
mount plastic package.  
Features  
Y
Wideband RF operation from 0.1 GHz to 2.0 GHz  
Y
No external biasing components necessary  
All input and output ports of the LMX2216 are single-ended.  
The LNA input and output ports are designed to interface to  
a 50X system. The Mixer input ports are matched to 50X.  
The output port is matched to 200X. The only external com-  
ponents required are DC blocking capacitors. The balanced  
architecture of the LMX2216 maintains consistent operating  
parameters from unit to unit, since it is implemented in a  
monolithic device. This consistency provides manufacturers

Y
Doubly balanced Gilbert cell mixer (single ended input  
and output)  
Y
Low power consumption  
Y
Power down feature  
a
significant advantage since tuning proceduresÐoften  
Y
needed with discrete designsÐcan be reduced or eliminat-  
ed.  
Small outline, plastic surface mount package  
Applications  
Y
The low noise amplifier produces very flat gain over the en-  
tire operating range. The doubly-balanced, Gilbert-cell mixer  
provides good LO-RF isolation and cancellation of second-  
order distortion products. A power down feature is imple-  
mented on the LMX2216 that is especially useful for stand-  
by operation common in Time Division Multiple Access  
(TDMA) and Time Division Duplex (TDD) systems.
