More specifically, the impedance value and Q value of two-terminal electronic components are measured by a measuring instrument such as a network analyzer. It relates to a method for correcting measurement errors when measuring by the shunt method.
- TRL is used as shown in Application Note 1287-9; In-Fixture Measurements Using Vector Network Analyzers ((C) 1999 Hewlett-Packard Company). (Through-Reflection-Load) net and SOLT (Short-Open-Load-Through) net are known.
- Figures la and lb show the measurement system using a network analyzer and the error models used in the SOLT correction TRL correction. .
- the electronic component 1 as a subject is connected to a transmission path formed on the upper surface of the measuring jig 2. Both ends of the transmission path of the measurement jig 2 are connected to a measurement port of a network analyzer (not shown) via a coaxial cable 3.
- S 1 1A ⁇ S 22A ⁇ or scattering coefficient of the transmission path including the subject, E DF, E RF, Chishita and coefficients E SF is one measurement port side, E LF, E TF Is the scattering coefficient on the other measurement port side.
- S 11A ⁇ S 22A is Chishita and coefficient of the object, e oo ⁇ en scattering coefficient of one measurement port side, the scattering coefficient of f 00 ⁇ f X 1 is other measurement port side It is.

- the transmission lines 5a to 5d are relatively easy to manufacture with a known scattering coefficient force S, and if total reflection is short-circuited, the characteristics can be predicted relatively easily. This enables correction. Therefore, in principle, the characteristics of the subject 1 alone can be measured.
- the through transmission line 5a is a so-called non-zero through
- the subject 1 is measured by connecting a shunt to the center of the through transmission line 5a.
- applying the TRL correction to a surface mount component, which is the subject causes the following problems.
- a common idea is to use a common coaxial connector and to connect the coaxial pin to the transmission line, which is a target, so as to avoid the effects of connector connection variations.
- the transmission line and the coaxial pin generally become thinner, so that the measurement reproducibility due to these positioning reproducibility increases.

Factors can be calculated, and measurement in the through state can be omitted.
- the measuring jig used in the present invention it is preferable to use a measuring jig having a transmission line in which a signal conductor and a ground conductor are formed on the same plane. This is because, in the correction work using the short chip and the measurement work using the test object, the short chip and the test object can be easily brought into contact with the signal conductor and the ground conductor at the same time. In addition, since the short tip and the test object can be pressed perpendicular to the transmission line, it is easy to secure a sufficient pressing load and the contact is easy to stabilize.

- the phase will be the same, so even if a short chip is connected at multiple positions and measured, the same characteristics will be measured. is there. Therefore, it is necessary to set the distance to a value excluding 1/2 of the signal wavelength or a multiple thereof, and it is preferable that the distance be 1/8 to 3Z8 of the signal wavelength. If the frequency bandwidth to be measured is wide, it is better to connect the short chip to four or more locations. Because if the frequency band is widened, it may be 1/2 or a multiple of the signal wavelength at one of the locations where the short chip is connected. It is necessary to make it remain.
