SiGe Semiconductor's SE2593A provides a complete 2.4 GHz and 5 GHz
WLAN multiple input, multiple output
solution including all of the circuitry required between the transceiver and the antennas.
Claimed by the company to be most integrated RF front-end module for IEEE 802.11n applications, it delivers optimal performance while enhancing size, system-level cost and manufacturability.
The SE2593A features 2.4GHz and 5GHz power amplifiers and low noise amplifiers, power detector, transmit and receive switch, diplexers and associated matching in a miniature land grid array package that measures just 5mm x 6mm x 1mm.
The new front- end module replaces up to 20 components which would be required to implement a discrete 1x1 MIMO solution. The small size allows multiple modules to create 2 transmit by 2 receive (2x2), 3x3 or 4x4 MIMO designs in support of higher bandwidth for streaming video applications, while accommodating shrinking form factors.
The SE2593A is claimed to be the smallest commercially available MIMO front-end to integrate a dual-band LNA. The integrated LNA improves total system noise figure, enhancing range and throughput to ensure better overall system performance. Eliminating the need for external LNAs also reduces system bill of material, and simplifies design, test and manufacture.
The SE2593A features the highest transmit power levels in the market, including +19 dBm in 2.5 GHz and +16 dBm at 5 GHz, at best-in-class ACPR performance. The device also includes an integrated power detector with 20 dB of dynamic range.
The high performance optimizes transmission of higher data rates over longer distances, thereby allowing systems to support emerging 802.11n applications such as video distribution, video streaming and high-speed data.
All RF ports are matched to 50 ohms to simplify PCB layout and the interface to the transceiver RFIC. The module is fully tested for ease of design and optimal yields.
The SE2593A is sampling to lead customers now. The device is shipping in volume now, priced at US $4.25 in 10k unit quantities.
