Matching the industry's smallest 1.5x1.5mm, 0.4mm-high footprint, Microsemi Corporation has unveiled the LX5514M power amplifier in a compact package. The new product is offered in a RoHS-compliant, 6-pin, 1.5x1.5mm, 0.4mm-high dual flat no lead package.

Microsemi (News - Alert) had recently introduced LX5553 and LX5543 front-end modules to continue its expansion into the fast-growing market for WLAN products used in space-constrained smartphones and other data-enabled cellular handset designs. Now, LX5514M power amplifier joins these products by supporting IEEE (News - Alert) 802.11b/g/n WLAN applications in the 2.4-2.5GHz frequency range. Streamlined to fit into a compact, ultra-low-profile package, the device is based on the company's proven LX5514 PA.

By improving performance and reliability, battery optimization, reducing size or protecting circuits, Microsemi's products offer individual components as well as integrated circuit solutions that enhance customer designs.

“Board area in today's smartphones is at a premium, and designers must squeeze more functionality into ever-smaller real estate," said Paul Pickle, vice president and general manager of Microsemi's Analog Mixed Signal Group. "The LX5514M enables designers to add WLAN capability in nearly half the space of the prior generation of 2mmx2mm PAs, and with a much lower profile that enables today's slim, sleek handset designs.”

The LX5514M power amplifier provides features such as 2.4 -- 2.5GHz operation, POUT=19dBm 3 percent EVM, Total current 130mA, InGaP HBT process technology for optimal performance and linearity, single-polarity 3.3V supply, power gain 27dB and so on. Also, Microsemi's broad portfolio of IEEE 802.11a/b/g/n WLAN, 802.16e WiMAX (News - Alert) and WiBro power amplifiers are used in a variety of applications.

Recently, the company announced PowerDsine PD-POE Extenders that double the powering reach of its PoE midspans to 200 meters. The company's semiconductors manage and control or regulate power, protect against transient voltage spikes and transmit, receive and amplify signals. The Power-over-Ethernet midspans, or PoE midspans as it is referred to, is presumably the first system in the market to supply reliable, uninterrupted power to Ethernet devices, claims the company.
