An RF isolator is a two-port device made of magnet and ferrite material to protect RF components or devices connected to one port from reflections from the other.

The following are common uses or applications for isolators in microwaves. ➤ In RF circuit design ➤ In test and measurement ➤ In microwave RF paths, as components to prevent any unwanted reflections.
Microwave equipment is mainly composed of four parts: (1) power supply part. Including rectification, filtering and voltage stabilization, among which the rectifier circuit is a key part of microwave equipment, which turns alternating current into direct current; The function of the filter is to filter out high-frequency clutter and interference signals; The function of the regulator tube is to stabilize the DC current at a certain value.
Typically, RF devices can be divided into active and passive devices. Active devices include microwave components such as PA, LNA and RFIC that require an external power supply, and passive devices include passive filters, power dividers, and other microwave components that can work without an external power supply.
Microwave devices can be divided into microwave electric vacuum devices, microwave semiconductor devices, microwave integrated circuits (solid-state devices) and microwave power modules according to their working principles and materials and processes.
