General Description
Features
The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/
MAX2327 high-performance silicon germanium (SiGe)
receiver front-end ICs set a new industry standard for
low noise and high linearity at a low supply current. This
family integrates a variety of unique features such as an
LO frequency doubler and divider, dual low-noise
amplifier (LNA) gain settings, and a low-current paging
mode that extends the handset standby time.
♦ Ultra-High Linearity at Ultra-Low Current and
Noise
♦ +2.7V to +3.6V Operation
♦ Pin-Selectable Low-Gain Mode Reduces Gain by
17dB and Current by 3mA
♦ Pin-Selectable Paging Mode Reduces Current
Draw by 6mA when Transmitter Is Not in Use
The MAX2320 family includes six ICs: four operate at
both cellular and PCS frequencies, one operates at cel-
lular frequencies, and one at PCS frequencies (see
Selector Guide). Each part includes an LNA with a high
input third-order intercept point (IIP3) to minimize inter-
modulation and cross-modulation in the presence of
large interfering signals. In low-gain mode, the LNA is
bypassed to provide higher cascaded IIP3 at a lower
current. For paging, a low-current, high-gain mode is
provided.
♦ LO Output Buffers
♦ LO Frequency Doubler (MAX2321)
♦ LO Frequency Divider (MAX2326)
♦ 0.1µA Shutdown Current
♦ 20-Pin TSSOP-EP Package
Ordering Information
The CDMA mixers in cellular and PCS bands have high
linearity, low noise, and differential IF outputs. The FM
mixer is designed for lower current and a single-ended
output.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

control inputs increase the current in the downconvert-
er. When the linearity requirement is not high, the cur-
rent is lower.
Detailed Description
Low-Noise Amplifier
Within its operating bands, each device in the
MAX2320 family (except the MAX2327) has three
modes of LNA operation: high gain, high linearity
(HGHL); high gain, low linearity (HGLL); and low gain,
high linearity (LGHL). The logic inputs control the LNA
mode as described in the AC Electrical Characteristics.
Use HGHL mode when extra-high LNA linearity is
required for cross-modulation suppression. Use HGLL
mode when the transmitter is off and cross-modulation
is not a concern. When the LNA changes modes, the
input VSWR change is minimal. Use LGHL mode for
receiving large signals and when high sensitivity is not
required. The MAX2327 LNA has only an HGLL mode.
Adjust the HGHL mode LNA linearity by changing
LO Output Buffers
The BUFFEN logic input turns the open-collector LO
output buffers on and off. This feature saves current if
the buffers are not required.
Operational Modes
Each device has logic input pins that control the differ-
ent operational modes listed in Tables 1–5.
MAX2320/MAX2321/MAX2326 Operation
The MAX2320/MAX2321/MAX2326 are dual-band, triple-
mode receivers that amplify and downconvert cellular-
and PCS-band signals. They consist of cellular and PCS
LNAs; cellular digital, cellular FM, and PCS digital mix-
ers; and cellular and PCS LO buffers. The MAX2321 has
an LO frequency doubler on-chip, so a single cellular-
band VCO can be used for both the cellular- and PCS-
band mixers. Selecting the PCS path activates the LO
frequency doubler. The MAX2326 has an LO divide-by-
two circuit, so a single PCS-band VCO can be used for
both the cellular and PCS mixers. Selecting the cellular
path activates the LO divide-by-two circuit. Three logic
input pins—BAND, GAIN, and LIN—control eight opera-
tional modes of the LNAs and mixers. The modes are
summarized in Table 1.

Downconverter
The downconverters in these devices are double-bal-
anced mixers. The PCS-band mixer and digital cellular-
band mixer share the same IF output ports. The cellular
band FM mixer has its own IF output to feed a different
filter. Adjust the downconverter linearity and current by
changing R

RBIAS

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.

noise figure. At the digital mixer outputs, keep the differ-
ential signal lines together and of equal length to ensure
signal balance. For best gain and noise performance, sol-
der the slug evenly to the board ground plane.
Layout Considerations
Keep RF signal lines as short as possible to minimize
losses and radiation. Use high-Q components for the LNA
input matching circuit to achieve the lowest possible
