Expanded RF power amplifier portfolio targets embedded WLAN applications
The SST12LP18E is a lower-cost, lower-voltage alternative to Microchip’s popular SST12LP14E power amp. The device offers the lowest operating voltage of any Microchip RF power amp, while operating at -20 to +85 degrees Celsius. The devices feature operating voltages as low as 2.7 V, linear output power as high as 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 2 mm x 2 mm x .45 mm QFN package. They are ideal for embedded WLAN applications where small size, high efficiency and low-battery voltage operation are required, such as in the consumer electronics market, in cell phones, game consoles, printers and tablets.
Many engineers are under pressure to extend battery life in their applications, and these new devices meet that demand by offering high power-added efficiency to reduce battery current drain, while their low operating voltages further extend battery life. The SST12LP17E’s matched input and output ports are easy to use and enable faster time-to-market. Additionally, this device requires no external RF matching components and requires only one external capacitor, taking up less board space.
The RF power amps are available in an 8-pin 2 mm x 2 mm x .45 mm QFN package. The fully matched, low-power SST12LP17E is priced at $0.48 each, in 10,000-unit quantities, while the low-power SST12LP18E is available for $0.29 each, in 10,000-unit quantities. Samples are available.
