MAX2320 General Description

The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/MAX2327high-performance silicon germanium (SiGe)receiver front-end ICs set a new industry standard forlow noise and high linearity at a low supply current. Thisfamily integrates a variety of unique features such as anLO frequency doubler and divider, dual low-noiseamplifier (LNA) gain settings, and a low-current pagingmode that extends the handset standby time.

The MAX2320 family includes six ICs: four operate atboth cellular and PCS frequencies, one operates at cel-lular frequencies, and one at PCS frequencies (seeSelector Guide). Each part includes an LNA with a highinput third-order intercept point (IIP3) to minimize inter-modulation and cross-modulation in the presence oflarge interfering signals. In low-gain mode, the LNA isbypassed to provide higher cascaded IIP3 at a lowercurrent. For paging, a low-current, high-gain mode isprovided.

The CDMA mixers in cellular and PCS bands have highlinearity, low noise, and differential IF outputs. The FMmixer is designed for lower current and a single-endedoutput.

All devices come in a 20-pin TSSOP-EP package withexposed paddle (EP) and are specified for the extend-ed temperature range (-40°C to +85°C).
