Product Overview
Keysight 11636C and 11636D Power Dividers operating from DC to 50 GHz and
67 GHz respectively, provide an excellent output power symmetry between the
two output ports. Their design features excellent amplitude and phase tracking to
ensure excellent source match for fault location applications using network
analyzers and also precise power division.
Any port may be used as an input, as the Keysight 11636C/D provides a
symmetrical power division. The 11636C/D can also be used as a power
combiner. When signals are input at two output ports, the sum of the two appears
at the input port. However, this is not recommended for ratio or source leveling
applications.

Features
11636C
– Broadband coverage from DC to 50 GHz
– Excellent amplitude (0.3 dB from DC to 50 GHz) and phase tracking
(±2° typical) minimizes amplitude and phase difference between the two
outputs to ensure an accurate power division.
– Low SWR of 1.67 at 50 GHz minimizes your measurement uncertainty
11636D
– Broadband coverage from DC to 67 GHz
– Excellent amplitude (0.4/0.65 dB from DC to 67 GHz) and phase tracking (±4°/
±7° typical) minimizes amplitude and phase difference between the two
outputs to ensure an accurate power division.
– Low SWR of 2.1 at 67 GHz minimizes your measurement uncertainty

Installation
Initial inspection
1Inspect the shipping container for damage. If the shipping container or
cushioning material is damaged, it should be kept until the contents of the
shipment have been checked for completeness and the instrument has been
checked both mechanically and electrically.
– Check for mechanical damage such as scratches or dents.
– Procedures for checking electrical performance are given under “Operator’s
Check” on page 21 or “Performance Tests” on page 22.
2If the contents are incomplete, if there is mechanical damage or defect, or if
the instrument does not pass the electrical performance test, contact the
nearest Keysight Technologies Sales and Service office (refer to “Sales and
Technical Support” on page 3). Keysight will arrange for repair or replacement
of the damaged or defective equipment. Keep the shipping materials for the
carrier’s inspection.
3If you are returning the instrument under warranty or for service, repackaging
the instrument requires original shipping containers and materials or their
equivalents. Keysight Technologies can provide packaging materials identical
to the original materials. Refer to “Sales and Technical Support” on page 3 for
the Keysight office nearest to you. Attach a tag indicating the type of service
required, return address, model number and serial number. Mark the container
FRAGILE to insure careful handling. In any correspondence, refer to the
instrument by model number and serial number.
