FIELD REPLACEABLE APPLICATION NOTES
These field replaceable connectors are easy to install and replace. The
hermetic seal is mounted into the circuit module wall and the connector
can be removed and replaced without destroying the hermeticity of the
circuit housing.
The field replaceable connector creates a transition from microstrip
circuitry to a coaxial transmission line. The SMK (2.92mm) seal pin
diameter is .012 (.030) to minimize the capacitive effects on the circuit
trace. For optimum electrical performance, the transition from the
hermetic seal to the microstrip trace must be properly compensated
which involves adjusting the microstrip trace width to minimize any
impedance discontinuities found in the transition area.
The plot shown below is representative of the typical return loss of a
Johnson field replaceable SMK connector. To produce the data shown
below, a test fixture is created using the Johnson SMK hermetic seal.
The fixture consists of a suitably thick spacer plate with the hermetic
seal mounted flush to both surfaces. Two connectors are mounted back
to back around the fixture and the VSWR of this test assembly is
measured. The calculated return loss trace shown is equivalent to the
square root of the measured VSWR of the test assembly. Since the
connectors tested are of identical design, it can be stated with fair
accuracy that the calculated data shown represents the response of a
single field replaceable connector and its transition to the hermetic seal.
Although we do not publish a VSWR specification for field replaceable
connectors, typical connector return loss can be expected to be better
than 20 dB through 40 GHz. A VSWR specification is not stated because
an industry standard method for testing field replaceable connectors
does not exist. The actual performance of the connector is dependent
upon the following:
1. For optimum electrical performance, we recommend the use of our
2. It is recommended that the hermetic seal be mounted flush with the

circuit housing. Tolerance variations between the hermetic seal and
machined housing do not always guarantee an optimum transition to
the connector. Some manufacturers recommend an additional
counterbore in the circuit housing to accommodate a solder washer
during installation of the seal. We do not recommend this type of
installation because, if the counterbore is not completely filled with
solder, electrical discontinuities may be created.
will effect electrical performance, as stated above. Several different
methods of hermetic seal mounting and seal pin to microstrip trace
attachment are used in the industry.
