Compact, high-efficiency RF power amplifier supports 5-GHz Wi-Fi applications

Microchip Technology Inc. has introduced the new SST11CP15 RF power amplifier for 5 GHz IEE 802.11a/n WLAN embedded applications. The device operates on the 4.9 to 5.9 GHz band, and offers a wide operating voltage of 3.3 V to 5 V.


The SST11CP15 features a high linear output power of 18 dBm at 2.5 percent EVM, using 802.11a OFDM 54 Mbps at 3.3 V, and 20 dBm at 5.0 V, and offers an output power of 23 dBm at mask compliance of 6 Mbps, at 3.3 V. The device is offered in a compact, 2 mm x 2 mm x .55 mm, 12-pin QFN package. It is ideal for 5 GHz WLAN applications where small size and high-efficiency operation are required, such as in wireless multimedia and MIMO applications for broadband gateway and consumer-electronics equipment.

The SST11CP15 meets the needs of designers who must reduce DC current consumption in their portable multimedia and MIMO applications. With its high power-added efficiency, the device reduces battery current drain and extends battery operation. The device’s 4.9 to 5.9 GHz linear operation enables 802.11a/n operation and increases data rates, while its small size is ideal for space-constrained applications.

Developers can begin designing today with the SST11CP15 Evaluation Board which is available now.

The SST11CP15 RF power amplifier is available in a 2 mm x 2 mm x .55 mm, 12-pin QFN package for $0.66 each, in 10,000-unit quantities. Samples are available now.
