MAX2530

19-2487; Rev 3; 1/04 Quadruple-Mode PCS/Cellular/GPS LNA/Mixers MAX2351/4/8/9/MAX2530/1/7/8 General Description The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/ MAX2531/MAX2537/MAX2538 family of single- and multiband LNA/mixer ICs is optimized for CDMA, GSM, and TDMA applications in both cellular and PCS bands. In addition, the MAX2530/MAX2531/MAX2537/MAX2538 ICs feature a GPS LNA/mixer signal path for E911 and traveler assistance applications. The cellular and PCS signals can be routed to either IF port. For example, one IF port can be connected to an IF filter with 30kHz bandwidth, 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 MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/ MAX2531/MAX2537/MAX2538 implement multiple LNA and mixer states, including high gain/high linearity, high gain/low linearity, midgain, low gain, and ultra-low gain. In high-gain/high-linearity mode, the high-IP3 LNA mi...
