25
3 dB 90° Card Couplers
HD-M Series
sFeatures
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
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
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.
4.Equipped with Tabs
Tabs permit direct mounting to surface circuits.
5.High Power Type
This type can be used with up to 100 W of power.
sProduct Specifications
Note: The frequency range and the maximum input power will differ depending on the products.
qThe test method conforms to MIL-STD-202.
