Sige Semiconductor has introduced the SE2579U Front End Module (FEM) for embedded and module applications markets, including WLAN-enabled mobile phones, digital cameras and personal media players.

Sanjiv Shah, director of product marketing at Wimax, and embedded WLAN at Sige said, ‘We designed the SE2579U to address the specific challenges faced by OEMs needing to operate direct-to-battery, and to facilitate Bluetooth/WLAN concurrent mode operation solutions.

‘The direct-to-battery operation does not require additional voltage regulation circuitry.

‘The high-output power of the module improves link budgets and the quality of data transfer and the design specifically resolves the issues of simultaneous BT/WLAN operation.

The SE2579U is a complete 802.11 b/g/n 2.4 GHz WLAN RF FEM with a Bluetooth port in a compact form factor (3 x 3 x 0.5 mm).

It is capable of simultaneous operation in both WLAN and Bluetooth receive mode without signal degradation found in current solutions.

The device provides all the functionality of the power amplifier, power detector, filter, switch, low noise amplifier, 2170 MHz notch filtering and associated matching.

The SE2579U provides a complete WLAN / BT RF single package solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver.

It is easy to deploy, with all critical matching and harmonic filtering integrated, while also offering a 50ohm interface to the antenna.

The SE2579U includes a power detector with 20dB of dynamic range and a digital enable control for transmitter power ramp on/off control.

It comes in a small lead and halogen free, ROHS compliant 3 x 3 x 0.5 mm, MSL 1, package and is suitable for integration in WLAN modules.
