We report a monolithic microwave integrated-circuit (MMIC) comb generator capable of producing a repetitive narrow pulse (7.1 ps pulse duration) with sharp edges (4.2 ps falling time). The circuit was designed in a 250 nm indium phosphide (InP) heterojunction bipolar transistor (HBT) technology using differential pairs. We characterized the output signal with a 110 GHz sampling oscilloscope and de-embedded the band-limited frequency spectrum of the pulse in the circuit reference plane. We measured a pulse duration of 7.1 ps and a peak amplitude of −0.333 V. In the frequency domain, the comb generator provided −48.7 dBm of output power at 110 GHz when the circuit is fed with a 1 GHz input signal.

采用 250 nm InP HBT 技术的 110 GHz 梳状发生器

我们报告了一种单片微波集成电路 (MMIC) 梳状发生器,能够产生具有尖锐边缘(4.2 ps 下降时间)的重复窄脉冲(7.1 ps 脉冲持续时间)。该电路采用 250 nm 磷化铟 (InP) 异质结双极晶体管 (HBT) 技术设计,使用差分对。我们使用 110 GHz 采样示波器对输出信号进行了表征,并在电路参考平面中去嵌入了脉冲的带限频谱。我们测量了 7.1 ps 的脉冲持续时间和 -0.333 V 的峰值幅度。在频域中,当电路输入 1 GHz 输入信号时,梳状发生器在 110 GHz 下提供 -48.7 dBm 的输出功率。
