MAX2701ECM+D
1.8GHz to 2.5GHz, Direct-Downconversion Receivers
neral DescriptionThe MAX2700/MAX2701 are highly integrated direct
downconversion (zero-IF) receivers designed for wide-
band wireless local loop (WLL) systems operating in
the 1.8GHz to 2.5GHz band. The MAX2700/MAX2701s’
zero-IF architecture eliminates the need for IF down-
conversion stages and the use of an IF SAW filter. This
reduces the overall receiver cost by reducing the com-
ponent count and required board space.
The MAX2700/MAX2701 have three main blocks: low-
noise amplifier (LNA), quadrature downconverter, and
baseband variable gain amplifiers (VGAs). The LNA is
a single-ended amplifier with selectable gain and shut-
down options. It provides a high input third-order inter-
cept point (IP3), which reduces cross-modulation and
gain compression due to high-level RF interference.
The quadrature downconverter section consists of two
highly linear double-balanced mixers driven by an
external local oscillator (LO) with a selectable LO dou-
bler. The double-balanced mixers are optimized to pro-
vide high input IP3 and minimum added noise. The
mixers’ high input second-order intercept point (IIP2)
helps minimize receiver desensitization due to high-
level AM-modulated interferers.
The two baseband VGAs in each channel provide 80dB
of total maximum gain and greater than 60dB of gain
control. The first AGC amplifier is optimized for low
noise, low power dissipation, and high linearity over the
entire gain range to ensure high gain compression per-
formance. An external lowpass filter between baseband
VGAs provides the required channel selectivity at the
adjacent channel. An integrated gain offset correction
loop circuit provides <0.3dB amplitude mismatch
between the I and Q channels.
The MAX2700/MAX2701 operate from a single +2.7V to
+3.3V power supply, drawing only 165mA of supply
current and 20μA in shutdown mode. Both devices are
available in small 48-pin TQFP packages with exposed
paddle (EP) for optimum high-frequency performance.

FRFIN= 1801MHz, PRFIN= -85dBm, FSPUR= 3601.5MHz, PSPUR= -60dBm. Measure IF at 1MHz and spurious at 1.5MHz at
the output. For better than 38dBc spurious attenuation response, output spurious level should be at least 10dB lower than
the IF signal level. In the (2 x LO) - (1 x RF) spurious product notation, LO denotes the frequency of the final LO driving the
I/Q mixers inputs.
Note 7:Mixer gain specifications are production tested over LO power range.
