General Description
The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/
MAX2531/MAX2537/MAX2538 family of single- and multi-
band LNA/mixer ICs is optimized for CDMA, GSM, and
TDMA applications in both cellular and PCS bands. In
addition, the MAX2530/MAX2531/MAX2537/MAX2538 ICs
feature a GPS LNA/mixer signal path for E911 and traveler
assistance applications. The cellular and PCS signals can
be routed to either IF port. For example, one IF port can be
connected to an IF filter with 30kHz bandwidth, while the
other port can drive an IF filter with a wider bandwidth. The
GPS band has its own IF port.
To optimize dynamic range at minimum current, the
MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/
MAX2531/MAX2537/MAX2538 implement multiple LNA
and mixer states, including high gain/high linearity, high
gain/low linearity, midgain, low gain, and ultra-low gain. In
high-gain/high-linearity mode, the high-IP3 LNA mini-
mizes desensitization in the presence of a large interfer-
ing signal. For the other gain states, the LNA current is
reduced to improve standby time. Each band is imple-
mented with a separate mixer to optimize performance for
the specific band, and each mixer provides multiple lin-
earity modes to optimize linearity and current consump-
tion. The ultra-low gain mode operates with very little
current, which results in significant power savings
because the handset typically spends most of its time in
this mode.
