6. Characteristics

6-1 Test Condition

Unless otherwise specified, the standard range of atmospheric

conditions for marking measurements and tests is as follows:

Ambient temperature:

20 ± 15°C

Relative humidity:

65 ± 20%

If there may be any doubt on results, measurements shall be made

within the following limits:

Ambient temperature:

20 ± 2°C

Relative humidity:

65 ± 5%

6-2 Measurement Method of L and Q

Test equipment:

Hewlett Packard RF Impedance analyzer 4191A

Fixture:

Hewlett Packard Test fixture 16092A

Measuring frequency:

500 MHz/1.0nH ~ 22nH (1.0nH ~ 15nH)

200 MHz/27nH ~ 100nH (18nH ~ 47nH)

1. Perform auto-calibration to the HP4191A .275" (7 mm) unknown connector connected to

0

Ω/0S/50Ω standard terminations.

2. Connected the test fixture 16092A.

Measure the open circuit admittance (Go, Bo), and the short circuit impedance (Ro, Xo).
