Stripline Non-reflective Terminations (Externally Mounted)

HRM-TM Series

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.
