单片GaN-FET放大器在连续波(CW)和脉冲工作条件下具有创纪录的c波段固态放大器输出功率。在5.0 GHz时,采用24 mm栅极外围的GaN-FET放大器可提供连续波100 W输出功率,线性增益为12.9 dB,功率附加效率为31%,脉冲输出功率为155 W,线性增益为13.0 dB。
A single-chip GaN-FET amplifier exhibits record output powers of C-band solid-state amplifiers under continuous-wave (CW) and pulsed operation conditions. At 5.0 GHz, the developed GaN-FET amplifier with 24 mm gate periphery delivered a CW 100 W output power with 12.9 dB linear gain and 31% power-added efficiency and a pulsed 155 W output power with 13.0 dB linear gain.
