Abstract
The balance operation between the efficiency and the linearity of RF power amplifier is the greatest challenging factor in wireless communication system. Amplifier is the most energy consuming element in a system, where more than 50% of the power produce is converted to heat energy as a waste. This situation gradually affects other devices in the transmitter system and can result to system performance reduction. A technique needs to be employed for dynamic amplification to counter balance the cost of energy consumption from base station and improve long battery life of the mobile equipment. This research presents a design of energy efficient balanced power amplifier to operate over the centre frequency of 2655MHz mobile LTE band, using Lateral MOSFET Transistor. In line up achievement, PAE is greater than 50% at 41dBm output power with 14dB transducer power gain, while achieving up to -59Bc linearized adjacent channel power ratio (ACPR) at 5190MHz, using a WLAN IEEE 802.16 OFDM Transceiver system.
