Which type of duplexers are the most common in radar systems?

In radar systems, waveguide and hybrid-ring duplexers are prevalent due to their efficient performance in separating the transmitted and received signals. Waveguide duplexers utilize physical waveguides to manage high-frequency signals, effectively minimizing losses and enhancing the overall system performance. Their design allows for excellent isolation between the transmitter and receiver, which is crucial for preventing interference and ensuring that the radar can accurately receive echoes from targets.

Hybrid-ring duplexers combine both electrical components and mechanical elements, offering additional flexibility and increased performance for certain applications. They can handle a significant amount of power and are effective in scenarios where space is a limitation, providing reliable functionality in compact radar systems.

Other types of duplexers, while they have their applications, do not match the popularity and effectiveness of waveguide and hybrid-ring designs in radar technology. Consequently, these two types of duplexers are favored in most radar systems for their performance characteristics in handling high frequencies, providing isolation, and supporting the complex needs of radar operations.
