The design and implementation of a broadband and linear HPA for TVWS are presented in this paper. The spectrum mask and transmitted power of HPAs for TVWS must be controlled and meet the regulations to minimize interference effects on the present broadcasting systems. The implemented HPA has the operating frequency of 470 ~ 698MHz with the maximum 48.63dB and minimum 43.45dB gain, input reflection coefficient of below –21.32dB, output reflection coefficient of below –4.29dB and the linearity of -45.24dBc at 28.79dBm output power.
