We present a compact W-band pulsed solid-state amplifier (SSPA) with WR-10 interfaces that delivers a record solid-state output power of 100 W, which is $> 2\times $ previously published waveguide combined W-band SSPAs. The SSPA leverages W-band gallium nitride (GaN) monolithic microwave integrated circuits (MMICs) and low-loss split-waveguide power combining. The amplifier utilizes an innovative modular approach to power combining 128 high-performance GaN MMIC power amplifiers (PAs). The SSPA is only $6.125'' \times 6.125'' \times 4.00''$ in size and weighs 10.48 lbs. This stand-alone SSPA also includes integrated power conversion and pulse modulation circuitry.

100W W 波段 GaN SSPA

我们展示了一种紧凑型 W 波段脉冲固态放大器 (SSPA),具有 WR-10 接口,可提供创纪录的 100 W 固态输出功率,即 $> 2\倍 $以前发表的波导组合 W 波段 SSPA。SSPA 利用 W 波段氮化镓 (GaN) 单片微波集成电路 (MMIC) 和低损耗分裂波导功率组合。该放大器采用创新的模块化方法对 128 个高性能 GaN MMIC 功率放大器 (PA) 进行功率组合。SSPA 仅 $6.125'' \times 6.125'' \times 4.00''$尺寸和重量为 10.48 磅。这个独立的 SSPA 还包括集成的电源转换和脉冲调制电路。
