Ferrite (FMT) high power waveguide duplexers allow systems to direct RF signals to different places using the same set of transmission lines. Ferrite Microwave Technologies duplexers are often utilized in radar system applications. These units reach end users in the Ka, K, Ku, X, C, S, L, and UHF bands. In addition to standalone units, FMT manufactures dual junction waveguide duplexers. All high-power units are delivered completely ready for radar platform integration.
FMT: Waveguide Duplexer Designs
FMT duplexers are available in frequencies ranging from 50MHz to 50GHz. We offer configurations for all power levels. Interfaces cover all standard industry configurations. We also offer mating to custom applications. End users of Ferrite Microwave Technologies components have qualified many end units, including: AWACS, TPS-78, ASR-9, TRC-170, SMART-L, HAWK, and many more. In many critical applications, high shock, vibration, and temperature extremes are factors.
We take rugged reliability into account on all of our designs. Most of FMT’s duplexers are set to perform in specific operating environments, with key performance requirements indicated by our clients. We support end users and clients with a range of environmental parameters. Whether the environment is land-based, mobile, naval, or airborne – FMT has the high-power solutions to deliver exacting duplexers in situations where failure cannot be tolerated.
How Do Waveguide Duplexers Work?
Essentially, duplexers work in a way that allow RF systems to direct signals to different places. This is completed utilizing the same set of transmission lines, whether waveguide or coaxial. Please see the diagram provided below for a visual represenation of how waveguide duplexers operate.
