SiGe Dual-Band LNA/Mixer ICs
General Description
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.
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.
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 (EP) and are specified for the extend-
ed temperature range (-40°C to +85°C).

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.
DC ELECTRICAL CHARACTERISTICS—MAX2320/MAX2321/MAX2326
(VCC = +2.7V to +3.6V, RRBIAS = RRLNA = 20kΩ, no RF signals applied, BUFFEN = low, LO buffer outputs connected to VCC through
50Ω resistors, all other RF and IF outputs connected to VCC, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC =
+2.75V and TA = +25°C, unless otherwise noted.)
