Product Description

Products Description

Transition waveguide (transition between adjacent waveguides)

The working frequency of adjacent waveguide transition is generally the adjacent overlapping frequency band or determined by the frequency range of high-frequency waveguide.

Transition between non adjacent transition waveguides

The working frequency of non adjacent waveguides is determined by the frequency range of high-frequency waveguides, which can generally be customized according to the requirements of users. Usually, the microwave signal is input from the small aperture waveguide port. Due to the large aperture of the output waveguide, there is the possibility of high-order modes near the output waveguide, so the performance of the waveguide connector and rear connecting element should take this into full consideration.

Rectangular circular transition

The rectangular circular transition waveguide uniformly converts the TE10 mode in the standard rectangular waveguide to the TE11 mode in the circular waveguide. Since the TE11 mode in the circular waveguide is not the lowest secondary mode, it is recommended to preferentially use the national standard by series circular waveguides compatible with international standards for the diameter of the circular waveguide. Generally, the H11 mode bandwidth of circular waveguide is lower than that of rectangular waveguide. Therefore, a rectangular waveguide can have three different sizes of circular waveguide aperture standards for selection. The best selection principle is to choose a larger circular waveguide aperture as far as possible when the frequency allows, so that VSWR, phase and attenuation are better. Non standard transition can be customized according to user requirements.

Product Description

1.Radar Cross Section

We provide state-of-the-art radar cross section measurement systems suitable for measuring small-scale test articles and/or full-scale vehicles depending on customer requirements.
2.Radome Testing
The military and commercial aircraft carry a vast array of antennas for specialized and vital functions. Communications, navigation, weather and fire control antennas must perform as specified to meet safety and mission requirements. Radomes must conceal and protect antennas without interfering with or degrading transmit/receive capabilities.
3.Satellite Antenna Testing
RF testing of flight hardware poses challenges that are unique to the space industry and antennas specifically, are often delicate and gravitationally sensitive. Minimizing or even avoiding motion of these antennas during testing is highly desirable for two reasons: Firstly, it minimizes risk to the antennas. Secondly, the standard gain horn antenna can be deployed with respect to a fixed gravity vector.
4.Wireles
Wireless networks rely on antennas and our products allow for the reliable characterization of these antennas. We offer test systems that are suitable for evaluation of electrically small handset or other UE antennas, as well as electrically large base station antennas.
