微波限幅器是一种功率调制器件,在小功率时,信号几乎无衰减地通过,但输入功率增大到一定值时,信号会产生很大衰减,这个值称为限幅器的门限电平。此后输入功率继续增长,输出功率保持几乎恒定。它通常用于保护功率敏感元件,如安装在接收机的高频放大器和混频器之前,来保护它们不被强信号烧毁。此外,限幅器也常用于微波扫频信号源或相位检测系统中,使输出信号幅度保持稳定。
PIN limiter Diode and Receiver Protector Module
Elite Microwave can provide solid-state
limiters up to 70kW peak or 500W mean at X-and. Product offerings
over all frequencies from L-Band to Ka-Band. Solid-state receiver
protectors are particularly suitable for TWT applications.
Receiver protectors isolate the sensitive
receiver from the damaging levels of RF power present when the RF
source transmits. When this power is no longer present, they go into
a low loss state, allowing the RF echoes to pass through to the
receiver for amplification and detection.

说明:
表中所列为一些常规的通用功能限幅器。实际工作中,限幅器基本上都是为整机需要而专门设计的。针对不同的工作频率、需承受的微波功率、微波脉冲宽度、占空比、要求的接口形式等条件,限幅器的设计也千差万别。南京恒电公司为不同客户设计制作了不同频段、不同功率、不同工作模式的多种限幅器,具有丰富的经验。
在接收系统中,限幅器和低噪声放大器往往是同时使用的。南京恒电公司在这两方面都具有一定的专长,因此将二者组合设计制造是我们的优势,这样不仅可以简化系统结构,更可以有效地提高系统性能。
微波限幅器 Microwave Limiter

微波限幅器是一种自控衰减器。当信号输入功率较小时无衰减通过,当输入功率增大到超过某一值时,衰减会迅速增大,这一功率值称为门限电平,输入功率超过门限电平后,输出功率不再增加。微波限幅器通常用在接收机的放大器或混频器的前面保护它们,免受强信号的影响而烧毁。在扫频仪或测相系统中可使输出幅度保持恒定。本公司开发的限幅器系列均为PIN限幅管芯设计的自驱动型限幅器,频率覆盖0.1-20GHz,平均功率容量达10W,并能制作低电平限幅器(10mW以下)。
主要参数定义
限幅电平:限幅器开始限幅时的功率值。
插入损耗:输入电平低于门限电平时输入信号损耗,一般在-10dBm下测试。
承受功率:能承受的最大输入功率(脉冲功率,脉冲平均功率,连续波功率)。
恢复时间:以输入脉冲终止开始,到限幅器损耗比插入损耗大3dB为止的时间。
