They are excellent for applications requiring precision, low loss high resolution tuning. The self-locking, constant torque drive mechanism eliminates the need for locking nuts and assures stable, noise free adjustment in application from to W band. microwave tuning element consists of a mounting bushing with an integral tuning rotor. eatures pplications High tuning resolution ombine filters - Interdigital filters xcellent tuning stability and very low dynamic noise Impedance transformers - ttenuators requency range from 0 to 100 Hz and more Impatt and unn oscillators asy to use, one hand tuning Microstrip and strip-line circuits old and chromate finish (other plating upon request) oaxial structures - Waveguide circuitry Metallic, dielectric and resistive types available ll tuning rotors available separately High reliability versions available upon request requency Hz Microwave Tuning lements Nominal requency Seletcion uide mm WV ILTRI RSISTIV INUTIV PITIV MTLLI TUNIN ROTORS 112

2 TMX MIROWV TUNIN LMNTS eneral matters - USHIN WITH MTLLI ROTOR Tuning elements with metallic posts are simple and straight-forward in design. ach tuning unit consists of two parts, a threaded mounting bushing and a selflocking rotor screw that won t vibrate loose. Noise free, low resistance contacting is maintained between both parts by the spring loaded webbing which forces the threads together. High Q tuning is possible from the smooth, short, non threaded slug with less exposed surface area than with standard screws.

3 MIROWV TUNIN LMNTS eneral matters TMX - USHIN WITH POWR SORNT ROTOR The T6950 series tuning elements are unique in that they absorb varying amounts of microwave power. The amount of power absorbed depends on the insertion of the slug into the waveguide or cavity. When properly mounted in the input or the output ports of microwave amplifiers, oscillators, etc., they may provide the test engineer a convenient means to trim the microwave power. The slug material is a magnetically loaded epoxide rod, chosen for its broadband lossy properties.

When a dielectric rod is introduced into a microwave cavity, the cavity appears electrically larger and the resonant frequency is lowered. This change in resonant frequency is dependent on the depth of dielectric rod insertion, the dissipation factor () which must be kept low to minimize circuit loss, the dielectric constant (K) of the material for tuning resolution, the diameter of the rod and its placement in the circuit. Ideal applications are unn diode and impatt oscillators. T SL T SL T SL T SL T SL mat.
