Microchip SST12LP17E/SST12LP18ERF power amplifiers

Microchip has expanded its RF power amplifier portfolio, with the SST12LP17E and SST12LP18E devices.

The SST12LP17E is said to be 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 the company’s SST12LP14E power amp. It offers the lowest operating voltage of any company RF power amp, while operating at -20 to +85°C. The devices feature operating voltages of 2.7 V, linear output power of 18.5 dBm at 2.5% 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% for IEEE 802.11b.

The amps are suitable for embedded WLAN applications where small size, high efficiency and low-battery voltage operation are required.
