MAX2771
Multiband Universal GNSS Receiver
General Description
The MAX2771 is a next-generation Global Navigation
Satellite System (GNSS) receiver covering E5/L5, L2,
E6, E1/L1 bands and GPS, GLONASS, Galileo, QZSS,
IRNSS, and BeiDou navigation satellite systems on a
single chip.
Designed on Maxim’s advanced, low-power SiGe BiCMOS
process technology, the MAX2771 offers the highest
performance and integration at a low cost. Incorporated
on the chip is the complete receiver chain, including
a dual-input LNA and mixer, followed by filter, PGA,
and multi-bit ADC, along with a fractional-N frequency
synthesizer, and crystal oscillator. The total cascaded
noise figure of this receiver is as low as 1.4dB.
The MAX2771 completely eliminates the need for exter-
nal IF filters by implementing on-chip monolithic filters
and requires only a few external components to form a
complete, low-cost GNSS RF receiver solution.
The MAX2771 is the most flexible receiver on the
market. The integrated delta-sigma fractional-N frequency
synthesizer allows programming of the IF frequency within
a ±30Hz (f
XTAL
= 32MHz) accuracy while operating with
any reference or crystal frequencies that are available in
the host system. The ADC outputs CMOS logic levels with
one or two quantized bits for both I and Q channels, or up
to 3 quantized bits for the I channel. The on-chip ADCs
can be bypassed and the analog I and Q signals output
for sampling with external ADCs. An analog monitoring
feature is provided that allows simultaneous output of the
on-chip ADC samples and the I analog signal.
The MAX2771 is packaged in a 5mm x 5mm, 28-pin,
TQFN package with an exposed paddle.
