The basic functional parts of microwave circuits made of hollow metal waveguides or cavities. Waveguide elements can form various waveguide networks or connect into various microwave circuits. Their functions are very similar to those of resistance, inductance, capacitance and resonance circuits at low frequencies, but most of them are distributed parameter elements. Generally, the waveguide can only transmit microwave signal or power, while the waveguide element can control the transmitted microwave signal or power, and complete various functions such as wave type conversion, impedance allocation, frequency separation or power distribution. It is a structure that guides electromagnetic wave, radio wave and sound wave with minimum energy loss and limits energy transmission. It is used to connect multiple devices and send signals over a long distance. It is used for radar, broadcasting, microwave communication, etc. Waveguides are often used in optical interferometers, nonlinear devices, photonic integrated circuits and optical communications.
Microwave waveguide components are mainly used in aerospace, national defense, radio communication, radar, electronic warfare and communication.
The most well-acceptable waveguide components includes waveguide adapters, waveguide couplers, isolator in microwave engineering and circulator, duplexer, pressure window. Market distribution: North American market, European market, Asia-Pacific market, South American market, Middle East and Africa.
With technology development, standard waveguide components is gradually into saturation. Increasing requirement is customized waveguide components for special application.
It consists of waveguides made of silver, copper, bronze, brass, aluminum, etc., with elliptical, circular and rectangular sections. Waveguide types are further divided into rectangular waveguide, circular waveguide, single ridge waveguide, double ridge waveguide and elliptical waveguide. The waveguide end users are further subdivided into aerospace and national defense, medical treatment, industry and others. Among them, other parts occupy the leading position in the market, accounting for US $769.7 million in 2021, which is expected to grow at a compound annual growth rate of 5.8% in the forecast period. Waveguides are usually used for communication purposes in spacecraft subsystems, and many satellite communication payloads use waveguide technology. Due to the increasing demand for limited frequency band, the industry is turning to higher frequency waveguide systems.
