A fully integrated linear CMOS power amplifier with high output power and dynamic range for WiMAX application

Wideband power amplifier based on Wilkinson power divider for s-band satellite communications

“…The design provides up to 12.4dB gain, but it suffers from limited bandwidth where covers from 5.6GHz to 6GHz (0.4GHz). Recently, many researchers have designed and developed power amplifiers, but most of the designed power amplifiers have been suffered from limited bandwidth, and high inter-modulation distortion which is considered a measure of linearity of the amplifier [14][15][16][17][18][19][20][21][22][23][24][25]. In [14], authors designed single stage wideband power amplifier with flat gain of 10-11.8 dB, and good input and output return loss.…”

“…But it suffers from low output power of 12.45 dBm and limited bandwidth of 600 MHz. Parallel cascaded class A and B power amplifiers based on CMOS technology for increasing linearity and efficiency have been proposed in [23]. The proposed design exhibits saturated output power of 32.5 dBm with power added efficiency (PAE) of 37.9 %.…”
