Seoul, March 23, 2015 – Microchip Technology (Korea Representative: Byung-Don Han), a global leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, announced the release of the new SST11CP22 5GHz Power Amplifier Module (PAM) supporting the IEEE 802.11ac ultra-fast Wi-Fi standard.

This PAM product provides 19 dBm linear output power with 1.8% dynamic Error Vector Magnitude (EVM) when modulating the MCS9 80 MHz bandwidth. The SST11CP22 provides 20 dBm linear output with 3% EVM in 802.11a/n applications, meets spectrum masks up to 24 dBm in 802.11a communication, and with RF harmonic output at this output power being less than -45 dBm/MHz, it can easily meet FCC standards through a system board.

For developers of Wi-Fi MIMO access points, routers, and set-top box systems, it is critical to maximize data rates and range while minimizing current consumption. The SST11CP22 combines low EVM with high linear output power to facilitate MIMO operation and significantly extend the range of 802.11ac systems in ultra-high-speed data transfer modes. This module is available in a space-saving 4mm x 4mm 20-pin QFN package, includes an output harmonic rejection filter, and features 50-ohm matching, requiring only four external components. The SST11CP22 is not only convenient to use and saves board space but also integrates with a linear power detector, enabling precise output control against temperature and 2:1 output mismatches. These characteristics play a very important role in 802.11ac Wi-Fi set-top boxes, routers, access points, and high-speed wireless video streaming devices.

Daniel Chow, Vice President of Microchip’s Radio Frequency (RF) business unit, stated, “Microchip’s RF power amplifiers have established a strong position in the WLAN market by combining stability and high power efficiency, which is achievable only using InGaP/GaAs HBTs. The new SST11CP22 also operates reliably with the lowest EVM, is easy to use, and has low harmonic radiation. This new PAM expands the range of ultra-high-speed 802.11ac systems and reduces manufacturing costs.”
