Microchip’s 5 GHz RF Power Amplifier for New IEEE 802.11ac Wi-Fi® Standard Delivers Low EVM at High Power for WLAN Applications
In-Stat predicts that one billion 802.11ac products will ship by 2015. The SST11CP16’s low EVM and high linear power provide an attractive option for set-top boxes, routers, access points and other Wi-Fi devices that require data rates of up to 3 Gbps for applications such as wireless streaming video. Additional features of this new PA include a 50 ohm on-chip input match and simple output match for ease of use and smaller board sizes. Additionally, the SST11CP16 includes a linear power detector that is temperature-stable and insensitive to voltage standing wave ratios.
“The SST11CP16 builds on Microchip’s industry-leading portfolio of InGap/GaAs HBT-based power amplifiers by providing high output power with extra-low EVM and the same reliable operation over temperature,” said Daniel Chow, vice president of Microchip’s Radio Frequency Division. “In conjunction with high-efficiency operation, this new power amplifier can significantly extend the range of 802.11ac systems.”
Existing 802.11 standards can also take advantage of the SST11CP16’s features, at the following performance rates:
- 802.11a: 3% added EVM for 54 Mbps at 22 dBm; spectrum-mask compliant up to 25.5 dBm using Orthogonal Frequency-Division Multiplexing
- 802.11n: Spectrum-mask compliant up to 24.5 dBm using High-Throughput 20 Mhz mode
