Isolator

The waveguide isolator uses the ferrite material in the waveguide and the additional constant magnetic field to control the transmission of electromagnetic waves in a certain direction, and the reverse is absorbed and isolated. The matching between systems reduces the impact of back-end reflected signals on the system, making them work independently and isolate each other.

circulator

The waveguide circulator controls the transmission of electromagnetic waves in a certain order through the ferrite material in the waveguide T-junction or in the waveguide network and an additional constant magnetic field. It can be used as a transceiver duplexer for pulse radar and a matching isolation for the intermediate stage of the system. effect.

A circulator is a three-port nonreciprocal device that transmits electromagnetic waves in a unidirectional loop. In the microwave system, the circulator is used to separate different frequency signals, so that each module in the microwave system is isolated from each other and does not interfere with each other; in modern radar communication, the circulator is often used as a duplexer.

We offer a range of high performance waveguide circulators. Frequency range: 0.76-40GHz, standard rectangular waveguide: BJ9-BJ320, relative bandwidth 25% internal standing wave 1.2; loss 0.3dB; isolation 20dB. Full waveguide bandwidth standing wave 1.3; loss 0.5dB; isolation 18dB. In addition, the waveguide specifications, flanges, indicators, etc. of the waveguide isolator can be customized according to user requirements.

Waveguide-to-coaxial converters are widely used in microwave measurement, microwave equipment, microwave systems and microwave engineering. According to the position of the coaxial output end, it is divided into two categories: orthogonal structure and termination structure. Standard waveguide types are rectangular, flat rectangular, medium flat rectangular, circular, single and double ridged. The types of coaxial connectors include N, TNC, L29, SMA, 3.5mm, 1.85, 2.92mm and 2.4mm, etc. Medium flat rectangular waveguide same frequency coverage: 1.7~10GHz, waveguide specifications from BB22 to BB84. VSWR≤1.2 (maximum); VSWR≤1.15 (typical) within the full waveguide bandwidth. It has the characteristics of wide frequency range, complete specifications and varieties, low voltage standing wave ratio and low insertion loss. The basic materials are copper and aluminum, and the surface treatment includes silver plating, gold plating, nickel plating, passivation, conductive oxidation and other treatment methods. The external dimension, flange, joint type, material, surface treatment and electrical index requirements of the product can be customized according to user requirements.
