Manufacturer:ALTERA Description: The MAX2531 multiband LNA/Mixer IC is optimized for CDMA, GSM, and TDMA applications in cellular band. The MAX2531 IC features a GPS LNA/mixer signal path for E911 and Traveler Assistance applications. The cellular signal can be routed to either IF port. For example, one IF port can be connected to an IF filter with 30kHz band-width, while the other port can drive an IF filter with a wider bandwidth. The GPS band has its own IF port. To optimize dynamic range at minimum current, the MAX2531 implements multiple LNA and mixer states, including high gain/high linearity, high gain/low linearity, mid gain, low gain, and ultra low gain. In high-gain/high- linearity mode, the 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. Each band is implemented with a separate mixer to optimize performance for the specific band, and each mixer provides multiple linearity modes to optimize linearity and current consumption. The ultra-low gain mode operates with very little current, which results in significant power savings because the handset typically spends most of its time in this mode. |
