Features
1.High Performance
The high frequency characteristics feature.
Extremely low loss and a high degree of matching.
2.Power Uniform Distribution and
90° Phase Difference Type
HD-0053M3-IH
HD-0195M3-DH
HD-0195M3-DH-1
HD-0900M3-CH-1
This is a one input, two output (or two input, one
output) power uniform distribution type having a
90° phase difference between the two outputs (or
two inputs).
3.Miniature and Lightweight
HD-0620M3-EH
HD-1700M3-FH
HD-3900M3-BH
HD-0313M3-FH
Corrosion-resistant aluminum is used for the cover
and the Hirose Electric original pattern design,
which uses a stripline triplate method, enables the
couplers to be extremely small and lightweight.
