      Microchip unveils InGaP/GaAs RF PA for 5 GHz Wi-Fi

      The compact SST11CP15 is a versatile power amplifier based on the firm’s indium gallium phosphide / gallium arsenide HBT technology.

      Provider of microcontroller, analogue and Flash-IP products, Microchip Technology, has revealed its 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 3.3V to 5V. The SST11CP15 features a high linear output power of 18 dBm at 2.5 percent EVM, using 802.11a OFDM 54 Mbps at 3.3V, and 20 dBm at 5.0V, and offers an output power of 23 dBm at mask compliance of 6 Mbps, at 3.3V.

      Offered in a compact, 2 mm x 2 mm x 0.55 mm, 12-pin QFN package, the device is ideal for 5 GHz WLAN applications where small size and high-efficiency operation are required. Ideal applications are 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. Its 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.

      “With the addition of the SST11CP15 to Microchip’s Wi-Fi power amp portfolio, Microchip now offers reliable, high-efficiency operation across the 5 GHz band,” said Daniel Chow, vice president of Microchip’s Radio Frequency Division. “This meets customer demand for a broad portfolio of reliable RF power amps, with high power-added efficiencies.”

      Developers can begin designing today with the SST11CP15 Evaluation Board (part # 11CP15-QUBE-K), which is available now, via any Microchip sales representative.

      The SST11CP15 RF power amplifier is priced at $0.66 each, in 10,000-unit quantities. Samples are available today, at http://www.microchip.com/get/TNQ6. Volume-production quantities can be ordered today at http://www.microchip.com/get/9JD6
