LTE/3G multimode RF transceiver enables deployment of HetNet small cell base stations

February 18, 2013 // By Paul Buckley
Maxim Integrated Products, Inc. has introduced a single-chip multistandard RF to Bits small cell radio transceiver which requires few external components to execute an all-band, multimode, multiple-input multiple-output (MIMO) radio design.

The MAX2580 design package also includes full system-level reference designs to shorten time to market. The RF transceiver is ideal for mobile operators 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 2x2 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.

T he MAX2580 supports all LTE bands from Band 1 to Band 41 with selectable channel bandwidths from 1.4 MHz to 20 MHz and also supports FDD-LTE, TD-LTE and WCDMA modes while enabling the full breadth of indoor and outdoor small cell solutions

The device’s 2x2 MIMO RF to Bits architecture; integrates complete RF front-end, IF amplifiers, fractional-N synthesizers, all decimation, interpolation and channel selection filters, plus a parallel JESD207 data interface.  The power amplifier (PA) pre-driver delivers  0 dBm output power level.

Full system-level reference designs are available for indoor and outdoor applications

MAX2580 is the newest LTE/3G small cell transceiver following the MAX2550-MAX2553 WCDMA and cdma2000 small cell transceivers. The MAX2580 is sampling now to qualified customers and will be available in the second half of 2013.

The MAX2580 will be on display at Maxim’s stand at Mobile World Congress 2013 in Barcelona, Spain on February 25-28. Maxim will be located in Hall 6 Stand 6G100.
