MAX2322 Operation
The MAX2322 is a lower-cost PCS-only version that can
be installed as a drop-in replacement for the dual-band
versions. It consists of a PCS LNA, PCS mixer, pin-
selectable LO frequency doubler, and LO buffer. Logic
input
SHDN
= V
CC
/ GND turns on/off the entire IC
except the LO buffer. The LOX2 logic input controls the
LO frequency doubler. LOX2 = GND disables the dou-
bler when using a PCS band VCO, and LOX2 = V
CC
activates the doubler when using a cellular-band VCO.
GAIN and LIN logic inputs control the MAX2322’s three
operational modes, as summarized in Table 2.
MAX2324 Operation
The MAX2324 is a lower-cost cellular-only version that
can be installed as a drop-in replacement for the dual-
band versions. It consists of a cellular LNA, cellular dig-
ital mixer, cellular FM mixer, and LO buffer. A
SHDN
logic input turns on/off the entire IC except the LO
buffer. GAIN and LIN logic inputs control the
MAX2324’s three operational modes, as summarized in
Table 3.
MAX2327 Operation
The MAX2327 is similar to the MAX2320 except it only
features an HGLL mode, and either LO output buffer is
selectable during shutdown. It consists of PCS and cel-
lular LNAs; PCS, cellular digital, and cellular FM mixers;
and PCS and cellular LO buffers. A
SHDN
logic input
turns on/off the entire IC except the LO buffer.
BAND
and MODE logic inputs control the MAX2327’s three
operational modes, as summarized in Table 4.
Applications Information
Cascaded LNA/Mixer Performance
The LNA and mixer design aims at optimizing cascad-
ed performance in all gain and linearity modes. In high-
gain, high-linearity mode, both the LNA and mixer have
a low noise figure, high gain, and high linearity. The
LNA has high gain to minimize the noise contribution of
the mixer, thus increasing the receiver’s sensitivity and
extra-high linearity for superior cross-modulation sup-
pression. The HGLL mode is used when the transmitter
is off and cross-modulation is not a concern. In low-
gain, high-linearity mode, the received signal is strong
enough that linearity is the primary concern. The LNA
gain is reduced for higher system linearity. Tables 5
and 6 summarize the cascaded performance.
S Parameters
The S parameters are listed in Tables 7–11. An electron-
ic copy is also available at www.maxim-ic.com
