Features
POWER COEFFICIENT: < 0.005 dB/dB/watt
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:
TEMPERATURE COEFFICIENT: < 0.0004 dB/dB/°C
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).
TEMPERATURE RANGE: -55°C to +125°C
TEST DATA: Insertion Loss, SWR, and Tracking measurements performed across the frequency band. Test data
available at additional cost.
CONNECTORS: Female 3.5mm connectors all ports--mate
nondestructively with SMA, 2.92mm and other 3.5mm
connectors.
CONSTRUCTION: Gold plated brass body; stainless steel
connectors; gold plated beryllium copper contacts.
