帶 SWR/PWR 拾音器的 1500W 低通濾波器

描述

Low Pass Filter With SWR/PWR coupler

This low pass filter directional coupler uses voltage doubler diode detectors to provide a DC voltage at the forward and reflected test ports. This coupler is ideally suited for VSWR protection circuits.

技術規格：

– 86-110MHz 1500 watts maximum.
– 9 階切比雪夫類型學。
