MAX2321
Adjustable, High-Linearity, SiGe, Dual-Band, LNA/Mixer ICs
General DescriptionThe MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/
MAX2327high-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).
