General Description
The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/
MAX2327/MAX2329 high-performance 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.
The MAX2320 family includes seven ICs: four operate
at both cellular and PCS frequencies, one operates at
cellular frequencies, one at PCS frequencies, and one
is configured as a dual PCS device (see
Selector
Guide
). Each part includes an LNA with a high input
third-order intercept point (IIP3) to minimize intermodu-
lation 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.
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.
All devices come in a 20-pin TSSOP-EP package with
exposed paddle and are specified for the extended
temperature range (-40°C to +85°C).

Note 1: See Tables 1–5 for operational mode selection.
Note 2: Operation is characterized for the frequencies specified in the conditions; for other frequencies in the band, see Tables
8–12 for LNA and mixer S parameters.
Note 3: Guaranteed by design, characterization, and production functional test.
Note 4: Guaranteed by design and characterization.
Note 5: For cellular band, RF inputs are -25dBm each tone at 881MHz and 882MHz, fLO = 1091MHz. For PCS band, RF inputs are
-25dBm each tone at 1960MHz and 1961MHz, fLO = 2170MHz. For IIP3 vs ICC trade-off, see
Typical Operating
Characteristics.
Note 6: The noise figure of the MAX2321 PCS-band mixer improves by approximately 2dB with LO input power = 0dBm.

_______________Detailed Description
Low-Noise Amplifier (LNA)
Within its operating bands, each device in the
MAX2320 family (except the MAX2327) has three
modes of low-noise amplifier (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 sup-
pression. 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 lin-
earity by changing RRLNA, and adjust linearity of the
other modes by changing RRBIAS.
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 RRBIAS (see
Typical Operating Character-
istics
). When the linearity requirement is high, the mode
control inputs increase the current in the downconvert-
er. When the linearity requirement is not high, the cur-
rent is lower.
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
low-noise amplifiers (LNA); cellular digital, cellular FM,
and PCS digital mixers; and cellular and PCS LO buffers.
The MAX2321 has a LO frequency doubler on-chip, so a
single cellular-band VCO can be used for both the cellu-
lar- and PCS-band mixers. Selecting the PCS path acti-
vates 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 operational modes of the LNAs and mixers. The
modes are summarized in Table 1.

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 = VCC/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 = VCC
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.
MAX2329 Operation
The MAX2329 is a receiver for the PCS band, featuring
two independent signal paths. It is ideal for systems
using half-band filters and/or duplexers for superior
spurious suppression. It consists of two PCS LNAs, two
PCS mixers, and an LO buffer. A SHDN logic input
turns on/off the entire IC except the LO buffer. PCSL/H,
GAIN, and LIN logic inputs control the MAX2329’s six
operational modes, as summarized in Table 5.
__________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 high-gain, low-linearity 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 pri-
mary concern. The LNA gain is reduced for higher sys-
tem linearity. Tables 6 and 7 summarize the cascaded
performance.
S Parameters
The S parameters are listed in Tables 8–12. An electron-
ic copy is also available at www.maxim-ic.com
/MAX2320/S_table/.
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 possi-
ble noise figure. At the digital mixer outputs, keep the
differential signal lines together and of equal length to
ensure signal balance. For best gain and noise perfor-
mance, solder the slug evenly to the board ground
plane.
