Two types of coaxial resonators are offered by Trans-Tech, a
quarter-wave short (λ/4) and a half-wave open (λ/2). The
quarter-wave has thick-film silver applied to one end. The
half-wave has both ends unmetallized.
Trans-Tech four dielectric materials are briefly summarized in
Figure 1.1 along with their recommended frequencies of use. The
Material Properties Chart (Figure 1.2) can be used to determine
the optimum material necessary for an application.

Quality Factor (Q) Specification — 1000 & 2000
The quality factors for various resonator profiles are shown in in
the following charts. The resonators are grouped by wavelength
type (λ/4 & λ/2), material (1000 & 2000), and profile (HP, EQ, SP,
LS, MP, SM). The listed Q value on each curve is the value guar-
anteed for the lowest operating frequency of each component
type. The Q increases approximately as the square root of
increasing frequency. Typical Qs are 10% to 15% higher.

Properties given for the ceramic materials used to produce the
coaxial line elements are measured for internal quality control
purposes. The electrical quality factor (Q) of the coaxial line
elements is determined primarily by the metallization. Typical
properties of the coaxial line elements are listed in the Coaxial
Resonator Quality Factor Specifications tables.

frequency range of 300 MHz to 6 GHz. Seven mechanical profiles
are offered to give the designer the greatest flexibility in selecting
the electrical quality factor (Q). The high profile (HP) has the
highest Q and size. The enhanced Q profile (EP) offers a high Q
and wide frequency offering. The standard profile (SP) offers a
compromise of electrical Q and size, and should be considered
the component of choice for most applications.

Trans-Tech offers four smaller profiles for occasions when avail-
able space is restricted. The low profile (LP), large profile (LS),
miniature profile (MP), and sub-miniature profile (SM) provide the
designer with a trade-off between electrical Q and compact size.
Trans-Tech low profile (LP) and large profile (LS) both have the
same outer physical dimensions. They differ in the dimension of
the inner diameter, which allows for different characteristic
impedances, and increases the options available to designers.
Overall comparisons can be determined from the given Q curves
or by utilizing Trans-Tech COAX Program.

The various profiles, materials and types available for the Trans-
Tech coaxial TEM mode resonators are summarized in the
following charts. You have a choice of two types, four materials
and seven profiles. This range of component variables should
meet most circuit design requirements. While the component is
manufactured to frequency, a formula is given so that the approx-
imate length can be determined. The selected resonant frequency

DATA SHEET • INTRODUCTION AND APPLICATIONS FOR COAXIAL RESONATORS AND INDUCTORS (300 MHz–6.0 GHz)
Values of inductance that can be achieved depend upon the sepa-
Ceramic Coaxial Inductors*
ration between the VCO frequency and the SRF of the coaxial line
element. Values less than 1 nH are not practical since the metal
connection tab itself has an equivalent inductance of this order.
Trans-Tech coaxial inductors are most frequently used in the res-
onant circuit of voltage-controlled oscillators (VCOs), where a
varactor provides the tuning capability. The designer is usually
confronted with trade-offs between high Q for best phase noise
and component size versus circuit board real estate. An algorithm
for selecting the correct Trans-Tech part follows. In addition,
Trans-Tech COAX Program can provide valuable assistance for
determining the correct Trans-Tech part. Application notes and
references give example circuits, basic principles, and some
helpful hints.
In our experience, equivalent inductances in the range of 3–20 nH
have been popular among designers of VCOs for wireless equipment.
Call for availability, utilize the Inductor Selection Guide, use the
COAX Program, or refer to the application notes for assistance
with ordering the correct part.
While there is no physical distinction between a coaxial resonator
and a coaxial inductor, the selection of an inductor for a VCO
begins by first knowing (from analysis or experiment) the equiva-
lent inductance that the active circuit, including the varactor,
must see. In general, the VCO active circuit loads the resonator,
lowering the resonator's self-resonant frequency (SRF). The situa-
tion is analogous to externally capacitively loading a discrete
parallel resonant L-C circuit.
While there is an approximate equivalent L-C circuit for the
coaxial resonator close to resonance, this model has limited
application.

The coaxial resonators and inductors are more accurately mod-
eled as a transmission line. Our application notes and references
delve further into this topic.

coaxial components is made with a one-port reflection measure-
ment on a network analyzer. The probe is moved into the inner
diameter (ID) of the device until the input resistance of the device
matches the terminal resistance of the network analyzer. This is
indicated by a 50 Ω circle on the Smith Chart display and is
known as “critical” coupling. The point on this circle where the
response is purely resistive (capacitance reactance equals induc-
tive reactance) is the point of resonance and will be defined by a
complex impedance of Z = 50 + j Ω. The Q is computed by
observing the frequency span between VSWR-2.616 (Z = 50
j50 Ω) on either side of f . The Q is defined as f /∆f.

The inductance parameter (L) is measured with an APC 7 mm
connector mounted flush with a conducting plane and a full one-
port calibration (open, short, broadband 50 Ω load) is performed.
The inductor is then clamped into place with the tab touching the
inner conductor and the metallized body touching the grounding
plane. The inductance (L) is measured at the frequency of use.
The impedance vector on the Smith Chart of an ANA gives the
necessary information where Z = R + jwL.

Characteristic Impedance
As shown in Figure 3, the characteristic impedance (Z ) of the
coaxial TEM mode components is a function of the profile dimen-
sions and the dielectric constant of the material. Z is reduced
over its air line value by the square root of the dielectric constant
of the material. At one-eighth wavelength, the short-circuit line
exhibits an inductive reactance while the open-circuit line

Trans-Tech coaxial components are compatible with standard
surface mount reflow and wave soldering methods. The HP
profile components may require mechanical support mounting
because of the larger size. Consult the factory for details.
Use silver-bearing solder such as SN62 (62Sn-36Pb-2Ag). Trans-
Tech tabs are pretinned to improve solderability. Additional
attaching methods include hot air gun, infrared source, soldering
iron, hot plate, vapor phase and others. The coaxial component
body is a ceramic and subject to thermal shock if heated or
cooled too rapidly. Figure 4 is the recommended soldering profile,
not to exceed 230 °C for a duration of about 10 seconds.
Repeatable results can be best achieved with air cooling only,
not quenching.
