Microwave Tuning Elements

Dielectric Resonator Tuners

Specifically designed for tuning dielectric resonator oscillators and filters, the rotor of these devices varies the distance between a tuning disk or rod and a dielectric resonator "puck". Standard models are compatible with a wide variety of puck diameters and mounting configurations, and operate in the frequency range of 2 to 18 GHz.

All dimensions are in/mm.

Notes:

1. Gold plated brass bushings and chromated brass rotors in the sizes shown above are standard. Other sizes and/or materials are available, contact factory.
2. Hardware modifications:
   1. For 0.04/1 x 0.04/1 slotted bushing, substitute "L" for "S" in model number.
   2. For ring nut (instead of hex nut), replace "N" in model number by "R".
   3. For no nut, replace "N" by "F".
   4. To add seal cap, add "C" at the end of the model number for a seal cap without a slot, and "B" for a seal cap with a screw driver slot.
3. Rotor adjusting slot is 0.16/4.0 x 0.020/0.51.
