Calibration and Verification Devices
The following section briefly describes the design and construction of all the
calibration and verification kit devices.
Offset Opens and Shorts
The offset opens and shorts are built from parts that are machined to the
current state–of–the–art in precision machining. The offset short's inner
conductors have a one–piece construction, common with the shorting plane.
This construction provides for extremely repeatable connections. The offset
opens have inner conductors that are supported by a strong, low dielectric
plastic to provide repeatability and reliability. Both the opens and shorts are
constructed so that the pin depth can be controlled very tightly, thereby
minimizing phase errors. The length of the offset opens are designed so that
the difference in phase of their reflection coefficients is approximately 180
°
at
all frequencies, with respect to offset short 3.
Above 50 GHz, the offset short calibration technique is used. Different
combinations of offset shorts using three different lengths are used to calibrate
frequency ranges from 50 to 75 GHz and from 75 to 110 GHz.
The calibration coefficients for these offset shorts are optimized for their
applicable bandwidths.
Offset Shorts (3 rings)
The offset shorts with three rings have three sets of calibration coefficients.
The lowband and broadband sets are optimized over the frequency range of DC
to 50 GHz. The highband optimized over the 50 to 110 GHz frequency range.
Again, female and male devices have different coefficients.
Verification Devices
The verification devices are designed to provide S-parameter measurement
comparisons over a broad range of signal levels. The matched thru
(adapter) checks the system performance for low loss and low reflection
characteristics. The mismatch thru (adapter) checks the system performance
over the medium to high reflection and medium loss ranges. The verification
devices in this kit are not totally a pass or fail system, but should be considered
probability indicators.
