Johanson High Power Resistive Products combine over 60 years of precision metal fabrication, ceramic processing, and assembly with proven design. Johanson offers complete design to manufacturing capabilities to provide standard and custom solutions to meet your needs.
Johanson Manufacturing Corporation 90' Hybrid, Dual Directional and Bi-Directional lines of coupler components with superior insertion loss and VSWR at frequency ranges from 30 MHz - 8 Ghz with power handling from 50W - 1000W. They are available in 2 different PCB mounting styles, tab version and surface mount version. JMC also has the capabilities to design and manufacture customized couplers to meet your unique electrical or mechanical specifications for both commercial and military applications.
With an overall height of only 0.350", these variable inductors are ideal for applications where low-profile circuit boards & high Q values are essential. The coils and PTFE cores are made to precision to guarantee a constant winding pitch and consistent relationship to the printed circuit board. Tuning is done by means of threaded PTFE and Non-Magnetic Copper Alloy core. JMC can provide custom variable or fixed inductors for any applications upon request. All Johanson Variable Inductors are RoHs compliant.
Air Capacitors are designed specifically for RF applications, VHF through microwave, and have become the industry standard of excellence. High Q and temperature stability are a result of proper attention to geometry and choice of optimum materials.
Non-Magnetic Capacitors are specifically designed for low magnetic signature applications such as Magnetic Resonance Imaging, Nuclear Magnetic Resonance, and other medical applications. These high stability Non-Magnetic Capacitors feature the one piece self locking constant torque construction for superior performance in very high strength magnetic fields.
Based around our Thin-Trim capacitors, Johanson's Cera-Trims are designed for use in harsh environments. The ceramic housing and color-coded epoxy seal protect the capacitor from solder fluxes and cleaning solvents. In use, the housing continues to protect the trimmer and provide rugged reliability.
In addition to Johanson's high performance line of low profile trimmers, Johanson Manufacturing offers a full range of surface mount capacitors that are designed and priced for high volume commercial applications.
Our Thin-Trim capacitors are ideal for applications where size and performance are most critical. These single-turn capacitors exhibit remarkable electrical characteristics for their small size. Useful up to 2 GHz, these trimmers are perfect for low-profile applications.
Our Seal-Trims are also built around the Thin-Trim capacitors. These capacitors are encased in a high performance polymer housing that is wave solderable and protects the trimmer from contamination.
Microwave Tuning Elements are a very cost effective method for the precision tuning of microwave filters, oscillators, and other resonant structures. They are excellent for applications requiring precision, low loss tuning permitting costly mechanical and electrical tolerances to be relaxed.
Giga-Trims® are tiny trimmer capacitors which provide a straight-forward technique for fine RF and microwave circuits by eliminating time consuming methods of abrasive trimming, cut and try adjustment techniques, and interchange of fixed capacitors.
Non-Magnetic Hardware are specifically designed for low magnetic signature applications such as Magnetic Resonance Imaging, Nuclear Magnetic Resonance, and other medical applications.
Johanson Manufacturing Corporation uses alumina (AL2O3), aluminum nitride (ALN) and beryllium oxide (BeO) to produce HTCC multilayer and single layer hermetic & non-hermetic packages for the photonic, wireless device and communication markets.
