Triple/Dual-Mode CDMA LNA/Mixers
________________General Description
The MAX2323/MAX2325 are low-noise amplifier (LNA) plus mixer ICs optimized for code-division multiple-access (CDMA) applications in both cellular and PCS bands. The MAX2323 addresses dual-band, triple-mode CDMA applications by providing switched signal paths for cellular FM, cellular CDMA, and PCS CDMA. The MAX2325 is a cellular-band dual-mode version. To optimize cellular-band dynamic range at minimum current, the MAX2323/MAX2325 implement four LNA states: high gain/high linearity, high gain/low linearity, midgain, and low gain. In high-gain/high-linearity mode, the adjustable high-intercept LNA minimizes desensitization in the presence of a large interfering signal. For the other gain states, the LNA current is reduced to improve standby time. The CDMA mixers are designed for high linearity, low noise, and differential IF outputs, while the FM mixer is designed for lower current and single-ended output. Each band is implemented with a separate mixer to optimize performance for the specific band. The MAX2323/MAX2325 can also be used in TDMA, EDGE, and W-CDMA phones.

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.

Note 1: Devices are production tested for functionality at frequencies stated; 30 units from 3 independent wafer lots, when one lot was at the upper process extreme, one lot was nominal, and one lot was at the lower process extreme, were characterized. The resulting standard deviation therefore includes process variations. Data sheet limits are 3 from the mean. Note 2: Operation over this frequency range requires the ports to be rematched for the desired operating range. Performance at various frequencies is indicated by the S-parameter data in Tables 3-7. Note 3: Specifications are based on RBIAS = 20k. ICC for all LNAs (except HGHL) and mixers are inversely proportional to RRBIAS. IIP3 can be traded for ICC by selecting other values of RRBIAS.
