Waveguide Isolators Broadband Octave RF Microwave Millimeter Wave
The waveguide isolator is a non reciprocal two port device that enables unidirectional transmission of electromagnetic waves, and isolation is used for reverse signal transmission. Therefore, an isolator is also known as an inverter. Mainly using techniques such as polarization separation and reflection to isolate the main signal from the reflected signal, thereby avoiding signal reflection and improving the transmission performance of the system; Used to control the unidirectional transmission of electromagnetic wave signals while reducing the impact of reflected signals on the system or source; It is also used to isolate reflected waves in circuits.
Application:
1. Isolation signal reflection: The broadband isolator adopts a special design that can limit the signal transmission in a certain direction while shielding the reflected signal, thereby avoiding the adverse effects caused by signal reflection. This can effectively isolate the main signal and the reflected signal, thereby improving the transmission performance and stability of the system.
2. Reduce device losses: As the frequency of the circuit increases, compression, distortion, and other adverse effects in the circuit also increase. RF isolators can reduce the interference of reflected signals, thereby reducing losses in the system and improving system performance.
In short, octave isolators are passive components used to isolate reflected signals and improve system performance, and are used in microwave, millimeter wave communication, and radar systems.
Qualwave supplies broadband waveguide isolators in a broad range from 2 to 47GHz. The power is up to 3500W.
