Latest LTE/3G multimode RF transceiver eases deployment of cell base stations

Maxim Integrated Products has introduced the MAX25801, a single-chip multistandard RF to Bits small cell radio transceiver. Highly integrated the solution requires very few external components to execute an all-band, multimode, multiple-input multiple-output (MIMO) radio design. The design package also includes full system-level reference designs to shorten time to market. The RF transceiver is suitable for mobile operators who are planning residential, enterprise, or outdoor small cell deployments in their next-generation heterogeneous networks (HetNet).

Anticipating the needs of next-generation HetNet solutions, the MAX2580 provides wideband frequency coverage with programmable channel bandwidths to support all LTE/3G bands and modes. In a single device, the MAX2580 integrates a complete 2×2 MIMO RF front-end, including fractional-N frequency synthesizers, high-speed data converters, and channel selection filters. Additionally, the MAX2580 features a standard JESD207 data interface to facilitate seamless connectivity with multicore LTE baseband processors.

Key advantages of the device include: high-performance radio supporting all LTE bands from Band 1 to Band 41 with selectable channel bandwidths from 1.4 MHz to 20 MHz; supports FDD-LTE, TD-LTE and WCDMA modes and enables the full breadth of indoor and outdoor small cell solutions.

Highly integrated with 2×2 MIMO RF to Bits architecture; the device integrates a complete RF front-end with IF amplifiers, fractional-N synthesizers, all decimation, interpolation and channel selection filters, plus a parallel JESD207 data interface; the power amplifier (PA) also pre-driver delivers 0dBm output power level.
