2.7V RF power amp from Microchip for embedded WLAN apps

Microchip Technology Inc has added the new SST12LP17E and SST12LP18E devices to its RF power amplifier portfolio. The SST12LP17E require only one DC bypass capacitor to achieve optimum performance. The SST12LP18E is a lower-cost, lower-voltage alternative to Microchip's popular SST12LP14E power amp. It works at a low operating voltage of 2.7V while operating at -20 to +85 degrees Celsius. The devices features linear output power of 18.5 dBm at 2.5 percent EVM using IEEE 802.11g OFDM 54 Mbps, and 23.5 dBm for IEEE 802.11b and a high power-added efficiency of up to 38 percent for IEEE 802.11b. The amps are offered in an 8-pin 2mm x 2mm x 0.45mm QFN package. They are suggested as ideal component for embedded WLAN applications where small size, high efficiency and low-battery voltage operation are required, such as in the consumer electronics market, in mobile phones, game consoles, printers and tablets.

The SST12LP17E requires no external RF matching components and requires only one external capacitor.

"With the release of these new power amps, Microchip can now offer customers the same reliable operation over temperature with even lower operating voltages," said Daniel Chow, vice president of Microchip's Radio Frequency Division. "Combined with high-efficiency operation, these low-operating-voltage devices extend the operating battery life for applications in the consumer-electronics industry."

Packaging: 8-pin 2mm x 2mm x .45mm QFN
Availability: Now in samples.
