MBC13720
Low Noise Amplifier
First SiGe:C Standard Product
Overview
Freescale Semiconductor’s MBC13720
low noise amplifier (LNA) with an on-chip
bypass switch is Freescale's first SiGe:C
standard product. This device uses the
SiGe:C module of Freescale's advanced
0.35 micron RF BiCMOS process. The
on-chip bypass switch improves the
dynamic range of the receiver with low
insertion loss. In addition to providing
improved performance, the bypass switch
helps conserve board space and reduce
system and manufacturing costs. The
device also provides selectable IP3
modes, low noise figure, selectable gain
settings and a standby mode to turn the
device completely off. Input and output
matching is performed externally to allow
maximum design flexibility.

Benefits to You
> Lowers system manufacturing costs due to
integrated, on-chip bypass switch and gain
control circuitry
> Improves dynamic range of the receiver with
integrated bypass switch
> Provides improved receiver sensitivity through
low noise figure
> Smaller battery for portable applications with
2.7V operation and low current consumption of
less than 20 microamps in standby mode
> Maximizes design flexibility and efficiency
with off-chip matching to optimize gain or
noise figure
> Provides higher circuit and system density with
ultra-small SOT-363 surface mount package
> Improved reliability due to lower power
dissipation
A Solution for these Questions
> Do you want to reduce part count and lower
your system and manufacturing costs by using
an LNA with on-chip bypass switch?
> Do you want to improve the dynamic range and
sensitivity of your receiver?
> Would you like to improve the flexibility of your
design by customizing the input/output
matching to optimize gain or noise figure?
> Does your design require that the battery size
be reduced with a supply voltage as low as
2.7V and low power consumption?
> Do you need to improve the IP3 performance
of your design?
> Do you want to reduce the PC board area for
your portable RF product?
