This study describes the design and measurement results of a wideband phased-array high-power transmission board for electronic warfare systems. The proposed high-power transmission board (HPTB) comprises a wideband gallium nitride (GaN) high-power amplifier and a true-time delay device to minimize the beam squint over wide bandwidths. The designed HPTB achieved an average output power level of more than 15.4 W with a continuous wave over the frequency range, and the flatness of the output power was up to 3.92 dB. In addition, when the input voltage standing wave ratio was less than 2:1, the isolation between the channels was more than 42.84 dBc. The amplitude and phase deviations between the channels were less than 2 dB and 2 ps, respectively. [ABSTRACT FROM AUTHOR] |
