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 cellular 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 intermodulation 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 extended temperature range (-40°C to +85°C).
