Microchip’s Amplifier Extends Range of Data Rate WLAN Systems
Microchip Technology (Chandler, AZ) recently announced its latest 2.4 GHz RF high-power amplifier—the SST12CP12—which adds support for the 256-QAM ultra-high data rate modulation.
- Linear output power of up to 23 dBm.
- Dynamic EVM as low as 1.8 %.
- MCS8 40 MHz bandwidth modulation.
- 25 dBm linear power at 3% EVM.
- Extends the range of IEEE 802.11b/g/n WLAN systems.
- Provides excellent power at the maximum 256-QAM data rate.
- Spectrum mask compliant up to 28.5 dBm for 802.11b/g communication, and
- Utilizes Orthogonal Frequency-Division Multiplexing (OFDM) to correct severe channel conditions without the need for complex equalization filters.
- Reduces board space with its small 3 x 3 x 0.55 mm, 16-pin QFN package.
Achieving the maximum data rate and longest range, while saving board space, is essential to WiFi access-point, router, and set-top-box designers. However, they also need to reduce power consumption, integrate input-matching functionality, and maintain temperature stability while ensuring transmission power control. The SST12CP12 power amplifier has a low operating current of 380 mA at 23 dBm, which enables more transmission channels and a higher data rate for each system. This amplifier also features 50 ohm 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.
