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.
