Card Couplers
HD-M Series
sFeatures
1.High Performance
The high frequency characteristics feature.
Extremely high degree of matching, and high
isolation.
2.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 miniature and lightweight.
3.Equipped with Tabs
Tabs permit direct mounting to surface circuits.
4.Full Coupling Variations
Full variations of degrees of coupling over 6 dB are
available.
5.Full Frequency Variations
Full complement of mobile radio frequencies.
sProduct Specifications
NOTE: The frequency range and the maximum usable power will differ depending on the model.
qThe test method conforms to MIL-STD-202.
qPlease see the specification items for details concerning VSWR, coupling,frequency sensitivity,and directivity.
