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
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
a significant advantage since tuning procedures often
needed with discrete designs can be reduced or eliminat-
ed
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
The LMX2216 is available in a narrow-body 16-pin surface
mount plastic package
