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 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 mix

Additional Information: Wireless Product Line Page Quick View Data Sheet for the MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/MAX2327 Applications Technical Support Objective: To develop a suitable pair of 110MHz IF matching circuits for this chip on-board application of the cellular-band dual-mode CDMA front-end IC. This project's requirement was to modify the analog AMPS' and digital mixers' matching circuits both to 110MHz IF, while meeting a specified gain, NF, and linearity spec. Here, we included the package dimensions of the bare die, because the application was for direct chip on board in an RF module application. The MAX2324 low-noise amplifier (LNA) plus mixer is designed for cellular-band CDMA cell-phone handsets, but it can also be used in TDMA, GSM, or EDGE applications. It offers two LNA gain states to meet the required CDM
