Common RF PA requirement

►Frequency: ► CMCC round1 and round2 equipments focus on bandA(1880MHz-1920MHz). From

round3, bandB(2010MHz- 2025MHz) equipments also become popular. Initial TD-LTE activities at 2.3-2.4GHz.

►Linearity requirement for power amplifier► 1.6MHz: 43dB for all temperature► 3.2MHz: 48dB for all temperature► (This is just a common requirement. Different customer has different requirement.)

►Output power requirement► 8 antennas smart antenna system: Moving from 2-3W to 5-10W, 6/9/12 carrier PA► Single antenna system: Moving from ~10W to 20-30W, 6/9/12 carrier PA► Others: For repeaters, A lot of different power levels from 0.5-20W
