5-GHz RF power amp supports IEEE 802.11ac Wi-Fi standard

The 5-GHz SST11CP16 RF power amplifier supports the new IEEE 802.11ac ultra high data rate Wi-Fi standard for 351 Mbit/s with 1.8% error vector magnitude (EVM) at 19 dBM output power, enabling a longer range. Additionally, the amplifier 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, this PA is offered in a 3 x 3 x 0.45 mm, 16-pin QFN package.

The part’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 Gbit/s for applications such as wireless streaming video. Additional features of this new PA include a 50 Ω 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. It meets 802.11a spectrum mask requirements at 25 dBm and 802.11n HT20 spectrum mask at 24.5 dBm.
