Microchip announces its latest 2.4GHz RF high-power amplifier, the SST12CP12, which adds support for the 256-QAM ultra-high data rate modulation. With its high linear output power of up to 23dBm at a dynamic EVM as low as 1.8% and MCS8 40MHz bandwidth modulation, as well as 25dBm linear power at 3% EVM, this amplifier significantly extends the range of IEEE 802.11b/g/n WLAN systems while providing excellent power at the maximum 256-QAM data rate. It is also spectrum mask compliant up to 28.5dBm for 802.11b/g communication, and uses Orthogonal Frequency-Division Multiplexing (OFDM) to correct severe channel conditions without the need for complex equalisation filters. Additionally, the SST12CP12 reduces board space with its small 3×3×0.55 mm, 16-pin QFN package.
Achieving the maximum data rate and longest range, while saving board space, is essential to Wi-Fi® access-point, router and set-top-box designers. However, they also need to reduce power consumption, integrate input-matching functionality and maintain temperature stability whilst ensuring transmission power control. The SST12CP12 power amplifier has a low operating current of 380mA at 23dBm, which enables more transmission channels and a higher data rate for each system. This amplifier also features 50ohm on-chip input match and simple output match, which is easy to use and speeds time to market. Additionally, the integrated linear power detector provides temperature stability and immunity to VSWR radio-wave reflection, for accurate output power control that ensures all of the power reaches its destination.
Key Facts:
• SST12CP12 combines high linear output power with low EVM in small package for longer range at maximum data rate
• Supports MCS8, HT40, spectrum mask and OFDM
• Low operating current enables more transmission channels and a higher data rate
