The improvement of efficiency on power am-CDMA cellular system. plifiers (PAs) has been a major assignment from dc to The verified system[4] [5] in this paper is composed microwave region. The class-E and F PAs, overdriven amof burst driven PA. The input of PA is switched by the plifiers with harmonics control are well known scheme PWM signals having the amplitude information of input to obtain the high efficiency on microwave PA. However, significant deterioration as same as the conventional amplifier signal. The operation point of PA can be classified in two is specifically inevitable issue in the linear operation. These cases; PAE optimum output and zero-output with minifacts draw efficiency reduction and modulation inaccuracy on mum power consumption. On this operation, high backoff the high backoff modulation such as OFDM. Recently, EER operation can be realized without efficiency reduction. (envelope elimination and restoration) and polar modulation are widely researched as a solution for these issues. In this In this paper, first, the basic configurahton and operaton work, a novel EER transmitter with burst-width modulation is explained. Next, PAE, EVM(error vector magnitude) and driven class-E amplifier system is verified on 64 QAM signal ACLR ( Adjacent Channel Leakage Ratio) of this system of 2.3GHz. As a result, it is confirmed that basic parameters are verified for 64QAM signal of 2.3GHz. As a result, it is on PA, EVM and ACLR are simultaneously improved.confirmed that basic parameters on PA, EVM and ACLR
