Microchip Technology introduced the SST12CP12 power amplifier. The SST12CP12 is a 2.4 GHz high-power and high-gain power amp. The chip supports the 256-QAM ultra-high data rate modulation. The SST12CP12 is available now for sampling and volume production, in a 3x3x0.55 mm, 16-pin QFN package. It is priced at $0.976 each, in 10,000-unit quantities.
Microchip SST12CP12 2.4 GHz High-Power and High-Gain Power Amplifier Features
- Power gain 34 dB
- Linear output power: 25dBm@3% and 23.5 dBm @1.8% dynamic EVM
- Spectrum compliant output power: 28.5 dBm for 802.11b/g and 26 dBm for 802.11/256QAM
- 3.0×3.0×0.55mm QFN package
The SST12CP12 features a high linear output power of up to 23 dBm at a dynamic EVM as low as 1.8% and MCS8 40 MHz bandwidth modulation, and 25 dBm linear power at 3% EVM. The Microchip amplifier 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 28.5 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. In addition, the SST12CP12 reduces board space with its small 3x3x0.55 mm, 16-pin QFN package.
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. In addition, 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.
