Microstrip Circulator
Microstrip Circulator is a commonly used RF microwave device used for signal transmission and isolation in circuits. It uses thin film technology to create a circuit on top of a rotating magnetic ferrite, and then adds a magnetic field to achieve it. The installation of microstrip annular devices generally adopts the method of manual soldering or gold wire bonding with copper strips.The structure of microstrip circulators is very simple, compared to coaxial and embedded circulators. The most obvious difference is that there is no cavity, and the conductor of the microstrip Circulator is made by using a thin film process (vacuum sputtering) to create the designed pattern on the rotary ferrite. After electroplating, the produced conductor is attached to the rotary ferrite substrate. Attach a layer of insulating medium on top of the graph, and fix a magnetic field on the medium. With such a simple structure, a microstrip circulator has been fabricated.

Band Pass Filter
A cavity duplexer is a special type of duplexer used in wireless communication systems to separate transmitted and received signals in the frequency domain. The cavity duplexer consists of a pair of resonant cavities, each specifically responsible for communication in one direction.
The working principle of a cavity duplexer is based on frequency selectivity, which uses a specific resonant cavity to selectively transmit signals within the frequency range. Specifically, when a signal is sent into a cavity duplexer, it is transmitted to a specific resonant cavity and amplified and transmitted at the resonant frequency of that cavity. At the same time, the received signal remains in another resonant cavity and will not be transmitted or interfered with.
