General Information
The 11667A power splitter is a two-resistor type power splitter for use in network
measurements where one arm of the power splitter is used for leveling or to supply a
reference signal for a ratio measurement.
Specifications
The specifications are listed in Table 1. These specifications are the performance standards or
limits, against which the power splitter may be tested. The typical operating characteristics
are provided in Table 2, “Typical Operating Characteristics,” on page 4. They are included as
additional information only; they are not specifications.

CAUTION Applying a signal greater than +27 dBm (0.5 Watts) may result in damage to the
power splitter.
Options
The standard 11667A power splitter is supplied with a female type-N on all three ports. The
Option 001 provides a type-N male connector on the input and two type-N female connector s
on the output ports. The Option 002 is supplied with a type- N female connector on the input
and APC-7 connectors on the output ports.
Description
The 11667A is a two-resistor power splitter for use in measurement systems where one arm is
an active arm. The active arm may be a leveling loop, or a reference channel of the network
analyzer for making a ratio measurement.
Power splitters used for wide-frequency coverage are usually of the resistive type. The
generalized form of a pow er splitter is shown in Figure 2, on page 5.
