Abstract
The design and implementation of a broadband and linear HPA(High Power Amplifier) for TVWS are presented in this paper. The spectrum mask and transmitted power of HPA for TVWS must be controlled and meet the regulations to minimize interference effects on present broadcasting systems. The implemented HPA has the operating frequency of 460 ~ 698MHz with $24.7{\pm}1dB$ gain, input reflection coefficient of below -25dB, output reflection coefficient of below -7.28dB and the linearity of -57.7dBc at 22.2dBm output power.
