New power amplifiers have been unveiled by Microchip, the SST12LP17E is described as the smallest fully matched power amp in its class, requiring only one DC bypass capacitor to achieve optimum performance.

The SST12LP18E is a lower-cost, lower-voltage alternative to Microchip’s SST12LP14E power amp and offers the lowest operating voltage of any of the company’s RF power amps, over an operating temperature range of -20 to 850C.

The devices feature operating voltages as low as 2.7V with linear output power as high as 18.5 dBm at 2.5% EVM using IEEE 802.11g OFDM 54 Mbps.

For IEEE 802.11b they offer 23.5 dBm and a high power-added efficiency of up to 38%. The amps come in an 8-pin 2mm x 2mm x 0.45mm QFN package making them ideal for embedded WLAN applications where small size, high efficiency and low-battery voltage operation is required.

These applications include consumer electronics such as in cell phones, game consoles, printers and tablets.
