TUNING ELEMENTS
METALLIC TUNING ELEMENTS
Metallic tuning elements have a metal
tuning rotor inside a
threaded mounting
bushing. A thread on
the rotor engages an
internal thread in the
bushing. The rotor
threads are slotted across their axis with
2 slots 180° apart. By compressing the
probe along its axis, the slots function as
a spring. The probe threads are pressed
firmly into flank-to-flank engagement
with the internal threads of the bushing,
eliminating backlash, while providing a
uniform adjustment torque that is self
locking.
Standard models are useful from 2 to 33
GHz. Metallic tuning elements can be
used to change the capacitive loading
within a waveguide, or any place a
metallic tuning probe is required.

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:
2.1 For slotted bushing, replace “S” in model number by “L”.
2.2 For ring nut (instead of hex nut), replace “N” in model number by “R”.
2.3 For no nut, replace “N” by “F”.
3. Rotor adjusting slot is 0.060/1.5 x 0.016/0.41 for bushings where “H” is
0.120-80, 0.13/3.3 x 0.020/0.51 for bushings where “H” is 0.190-64, and
0.16/4.0 x 0.020/0.51 where “H” is 0.234-64.

MICROWAVE TUNING ELEMENTS
DIELECTRIC TUNING ELEMENTS
The use of a dielectric rod (instead of a
metallic probe) for
the tuning element
will provide the lowest loss tuning for
high frequency applications. When the
dielectric rod is introduced into a microwave cavity it has the
effect of making the cavity electrically
larger, and lowering the resonant frequency. Dielectric tuning elements are
excellent for adjusting the frequency of
Gunn diode and IMPATT oscillators.

TUNERS
Specifically
designed for
tuning dielectric resonator
oscillators and
filters, the rotor
of these
devices varies the distance
between a tuning disk or rod of
various materials 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.

MICROWAVE TUNING ELEMENTS
LC TUNING ELEMENTS
SG-670B
MODEL NO.
Variations of the standard metallic units,
LC tuning elements
are designed specifically for filter applications. These devices
provide a fixed post
length which is
extended by rotating the metallic rotor.
A typical application is a direct-coupled
TEM mode coaxial configuration. The
post length is selected to cover the
desired range. A circuit is designed
around the tunable post so that each
section approximates 76 ohms for optimum resonator Q and high selectivity.

The use of a lossy rod
material for the rotor
of the tuning element
provides a convenient and effective
means of trimming
the microwave
device in a waveguide or cavity. The amount of power
absorbed is a function of the depth of
insertion of the rod into the waveguide
or cavity. Standard models are ideal for
frequencies of 1 to 18 GHz.
