Power amplifier supports new IEEE ultra-high data rate Wi-Fi standard
Sept. 27, 2012
Microchip Technology Inc. announces the expansion of its RF portfolio with the new SST11CP16 5-GHz power amplifier (PA).
The SST11CP16 5-GHz power amplifier (PA) supports the IEEE 802.11ac ultra high data rate Wi-Fi standard for 351 Mbps with 1.8% Error Vector Magnitude (EVM) at 19 dBM output power, enabling a longer range. Additionally, the SST11CP16 provides low operating current of 360 mA at 22 dBm, which enables more transmission channels at a higher data rate, per system. To conserve space, the new PA is available in a 3 x 3 x 0.45-mm, 16-pin QFN package.
The SST11CP16’s low EVM and high linear power provide an 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. Other features of the 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.
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
