RF / Microwave Ferrite Circulators
TRAK Microwave ferrite circulators provide non-reciprocal transmission paths. These high performance circulators have three or more ports arranged such that energy entering a port is coupled to an adjacent port, but (typically) not coupled to the other ports.
TRAK Microwave has a long legacy in the design and production of high reliability microwave circulators, and we have earned the industry’s highest marks for innovative, dependable, high quality RF and microwave circulators and integrated circulator assemblies. Our devices are often recognized for their duplexing (dual junction) capability, excellent bonding pads, and low-mass characteristics.
We offer a broad circulator product base from low mass/high volume micro-strip devices for phased array radar applications, to high power dual-circulator/detectors for airborne communications. TRAK specializes in custom engineered solutions for unique customer needs including high power handling in compact packages, filtering out of reject band requirements, reverse power detection, and power combining.

TRUE Surface Mount Circulators
TRAK is introducing a NEW Line of True Surface Mount Circulators that offer competitive performance to micro-strip circulators, are compatible with solder reflow profiles, and are available on tape and reel. Standard devices are being developed for X, C, and S radar bands.
Coaxial Microwave Circulators
Coaxial circulators generally use SMA female connectors. Other connector orientations are also available. TRAK connectors meet the dimensional interface requirements of MIL-C-39012, and are torque tested. These coax circulators are ideal for military and space as we have a demonstrated and extensive program heritage.
Key features of our coax microwave circulators include: a one-piece stainless steel housing (providing excellent EMI performance, mechanical integrity, and corrosion resistance); compact size; and an extensive catalog of optional models with customization and integration capability.
Drop-In Microwave Circulators
Drop-in microwave circulators from TRAK have tab leads for interconnection with microstrip or stripline circuitry. These drop-in microwave circulators are ideal for military and space as we have a demonstrated and extensive program heritage.
Key features of our drop-in microwave circulators include: a one-piece stainless steel housing (providing excellent magnetic shielding, mechanical integrity, and corrosion resistance); extended center conductor tabs; no internal solder joints; compact size; and an extensive catalog of optional models with customization and integration capability.
Monolithic Micro-strip Microwave Circulators
Monolithic micro-strip microwave circulators from TRAK utilize a metallized ferrite substrate mounted on a ferrous carrier. Interconnections are typically gold wire bonds or ribbon bonds. These devices are often used in MIC modules for phased-array radar systems. These micro-strip microwave circulators are ideal for hybrid assemblies deployed in military and space applications, as we have a demonstrated and extensive program heritage.
High Power Integrated Dual-Circulator/Detector for Airborne Communications
Model FMP146 is a unique 4-port, dual junction module featuring forward and reverse power detection, a high power BeO load, a lightweight aluminum body, and 75 watts CW power (forward and reverse).
Advanced Engineering Tools
For our more complex junction and integrated devices, TRAK utilizes HFSS to analyze complex microwave structures to optimize interfaces and ferrite junction performance, predict thermal rise inside the ferrite junction, and calculate voltage peaks to predict dielectric breakdown.
With the addition of Maxwell magnetic simulation we can also analyze: magnetic field proximity effects; magnetic moments; magnetic return path efficiency; the shift in RF performance from small signal to high power operation, and create highly accurate models of devices with non-uniform fields such as in our microstrip circulators.
Design and drafting is done in SolidWorks, allowing us (and you) to view mechanical fit prior to cutting metal.
Environmental Testing
TRAK has the capability to conduct complete environmental testing of your microwave circulators in house including shock, vibration, moisture and thermal vacuum testing to the highest military and space requirements.
