摘要

近年来，为了降低成本，T/R模块需要具有高功率能力的表面贴装终端。在氮化铝上使用大电阻膜的终端被认为是一种高功率使用的方法。然而，它们存在一个问题，即难以获得宽带终端。因此，我们提出了一种在电阻膜中带有短桩的新型终端。这种终端可以通过与打开的存根产生输入信号的共振来分散热量。因此，与传统终止相比，所提出的终止将表面损失密度提高了50%。此外，我们还发现，在43.3%的带宽范围内，制作的端部具有小于−20B的反射系数特性。

Termination with Stubs in Resistive Film

In recent years, T/R modules have required surface mount terminations with high-power capability for cost reduction. Terminations with large resistive film on aluminum nitride have been proposed as a method for high power use. However, they have a problem that it is difficult to obtain the broadband terminations. Therefore, we propose a novel termination with stubs in resistive film. This termination can disperse heat by resonating an input signal with open stubs. Hence, the proposed termination improved surface loss density by 50% compared to the conventional one. In addition, we show that the fabricated termination has the reflection coefficient characteristics smaller than −20B in the bandwidth of 43.3%.
