Designing with the MAX2538 Family of Single- and Multi-Band LNAs and Downconverters
The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/MAX2531/MAX2537/MAX2538 family of single- and multi-band LNAs and downconverters are optimized for CDMA, GSM, and TDMA applications in both cellular and PCS bands.
The MAX2530/MAX2531/MAX2537/MAX2538 ICs feature an additional GPS LNA and downconverter 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.
