Microchip announces its new SST11CP22 5GHz Power Amplifier Module (PAM) for the IEEE 802.11ac ultra-high data-rate Wi-Fi® standard. This PAM
delivers 19dBm linear output power at 1.8% dynamic Error Vector Magnitude (EVM) with MCS9 80MHz bandwidth modulation. Additionally, the SST11CP22 delivers 20dBm linear power at 3% EVM for 802.11a/n applications, is spectrum mask compliant up to 24dBm for 802.11a communication, and has less than -45dBm/MHz RF harmonic output at this output power, making it easier for the system board to meet FCC regulations.
Achieving the maximum data rate and longest range, while minimising current consumption, are essential to designers of Wi-Fi MIMO access-point, router and set-top-box systems. The SST11CP22’s low EVM and high linear power facilitate MIMO operation and significantly extend the range of 802.11ac systems in ultra-high data-rate transmission mode. The module, housed in a space-saving 4×4 mm,
20-pin QFN package, includes an output harmonic rejection filter and is 50Ohm-matched, requiring only four external components. It is easy to use and reduces board size. Additionally, the integrated linear power detector provides accurate output power control over temperature and 2-to-1 output mismatch. These features are critical for 802.11ac Wi-Fi set-top boxes, routers, access points and wireless video streaming devices that operate at high data rates.
