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 50
The output port is matched to 200
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
