Power Splitters & Dividers

Model 1534

dc to 40.0 GHz

Broadband Resistive Power Splitter

1 Watt

(Matching), Subminiature, SMK Connectors

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 50

Ω.

Some examples are:

o A dual-channel insertion loss measuring system where

the resistive power splitter provides a reference and a

signal channel for ratio meter.

o A parallel IF substitution insertion loss measuring

system where the resistive power splitter provides a

sampled output for leveling the signal source.

o A precision power source where a power meter of

known characteristics is used, either by ratio or leveling

to provide a calibrated output.
