摘要

这封信介绍了一种功率限制器，当大功率进入射频接收器时，它可以限制输入功率以保护接收器。当功率限制器接收到较大的功率信号时，一个PIN二极管被打开，通过降低阻抗来限制输入功率。根据PIN二极管与功率限制器输入、输出传输线并联的方法，分析了功率限制器的特性。通过在腔内嵌入PIN二极管并减小导线长度，设计并实现了功率限制器，以减小寄生电感。在s波段，功率限制器的插入损耗低于0.5 dB，反射损耗特性低于15 dB。此外，它在3.5 GHz时实现了21.8 dBm的输出P1dB。

Power Limiter with PIN Diode Embedded in Cavity to Minimize Parasitic Inductance

This letter introduces a power limiter that limits the input power to protect the receiver when a large power enters the radio frequency receiver. When the power limiter receives a large power signal, a positive-intrinsic-negative (PIN) diode is turned on to limit the input power by lowering the impedance. We analyzed the characteristics of the power limiter according to the method of connecting the PIN diode in parallel with the input and output transmission lines of the power limiter. By embedding a PIN diode into the cavity and minimizing the length of the wire, a power limiter was designed and implemented to minimize parasitic inductance. In the S-band, the proposed power limiter’s insertion loss was below 0.5 dB, and the reflection loss characteristics were below 15 dB. Furthermore, it achieved an output P1dB of 21.8 dBm at 3.5 GHz.
