Features
These resistive power splitters are intended for RF and
wireless applications in which one of the two outputs is
included in a leveling loop or is used as a reference in a
ratio system, for the purpose of providing an output signal
whose source impedance is essentially matched to 50Ω.
Some examples are:
o
A dual channel insertion loss measuring system
(ratio).
o
A parallel IF substitution insertion loss measuring
system (ratio or ALC loop).
o
A precision power source (ratio or ALC loop).
TEST DATA:
Insertion Loss, SWR, and Tracking measure-
ments performed across the frequency band. Test data
available at additional cost.
CONNECTORS:
Type N female connectors per MIL-STD-
348 interface dimensions - mate nondestructively with
MIL-C-39012 connectors.
