| Abstract: | 4G mobile phone wireless access system by RF/MW integrated circuit technology is presented in this paper. Antenna, net matcher and amplifier are mounted on one substrate; therefore it is less bulky, easily in shape with other parts of system, low power consumption and high stability. Prediction of magnitude-frequency characteristic shows that the designed 4G mobile phone wireless access system has gain of 31 dB at the 5 GHz center frequency with its bandwidth more than 100 MHz, satisfying the requirement of the mobile terminal of 4G wireless communication. |
