Terminations for the Division Part of a Wilkinson Divider (100 ohms Type)
HT Series
I
Features
1.High Performance
These wide bandwidth/ultra high matching non-
reflective termination use Hirose Electric original
high frequency matching technology.
2.Equipped with Tabs
Termination are equipped with tabs to permit direct
mounting to Wilkinson type flat circuits.
3.High Power and Small Size
Beryllia is used for the material of the resistance
element to enable the termination to be of small
size and used with high power.
