LTE Mixer Array of 0.5W High Output Power
The proposed design was applied to a 1.7 GHz mixer array power amplifier in an LTE system.The proposed design uses mixer units as array combinations and achieves combination by converging output currents at the mixer output point,utilizing the Balun transformer to convert double-ended signals to single-ended signals.In transmitter applications,a power amplifier designed using this method can realize a transmitter front-end circuit with a fully integrated CMOS and 0.5W of input power.The results of the 16-unit simulation were as follows: the output power was 27dBm and the power-added efficiency(PAE)was 19%.There was an overall supply voltage of 3V,and the chips area was approximately 1.512×1.285 mm.
