Stripline Non-reflective Terminations (Externally Mounted)
HRM-TM Series
56
sFeatures
1.High Performance
These wide bandwidth/high matching non-reflective
termination use Hirose Electric original high frequency
matching technology.
2.Stripline External Mounting Type
These termination are constructed to mount externally to
the housing of a microwave device.
3.High Degree of Matching Type and
Economical Type
To suit the application, a type that features a high degree
of matching (with VSWR of 1.15 max from DC to 18
GHz) and an economical type (with VSWR of 1.15 max
from DC to 8 GHz, and VSWR of 1.25 or less from 8 to
12.4 GHz) are available.
4.Applications
Ideal used as a dummy load for coaxial type circulators,
directional couplers, hybrid dividers, and other devices.
