The SST11CP22, a 5GHz power amplifier module, has been developed by Microchip to support devices using the IEEE802.11ac Wi-Fi standard.
According to Microchip, the device delivers a linear output power of 19dBm at a 1.8% dynamic Error Vector Magnitude (EVM) and with an MCS9 bandwidth modulation of 80MHz.
Achieving the maximum data rate and longest range, while minimising current consumption, are said by Microchip to be 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 extend the range of 802.11ac systems in high data rate transmission mode.
The module, housed in a 4 x 4mm 20pin QFN package, includes an output harmonic rejection filter and is 50? matched, requiring only four external components.
Additionally, an integrated linear power detector provides accurate output power control over temperature and 2-to-1 output mismatch: features said to be critical for 802.11ac Wi-Fi devices at high data rates.
