OPERATING AND MAINTENANCE MANUAL
FOR POWER DIVIDERS
1. INTRODUCTION
This manual describes the 11, K240 and V240 Series
Power Dividers (Figure 1). It provides specifications
and a list of precautions the user should observe
when using them.
2. DESCRIPTION
ANRITSU precision power dividers are produced in
three models:
•11 Series, DC to 3000 MHz using N connectors
•K240B, DC to 26.5 GHz using K Connectors®
K240C, DC to 40 GHz using K Connectors
•V240C, dc to 65 GHz using V Connectors®
All models are symmetrical, three-resistor tee
designs that can be used in applications where
signals must be accurately divided or combined.
K Connectors are compatible with GPC–3.5 and
SMA. V Connectors are compatible with GPC 2.4
connectors. All three models have exceptional
amplitude and tracking characteristics.
3. SPECIFICATIONS
Table 3 provides performance specifications.
4. PRECAUTIONS
ANRITSU precision power dividers are high-quality,
precision laboratory components and should receive
the same care and respect afforded other such
devices. Complying with the following precautionary
notes will guarantee longer component life and less
equipment downtime due to connector failure. Also,
such compliance will ensure that RF component
failures are not due to misuse or abuse — two failure
modes not covered under the ANRITSU warranty.
a. Beware of Destructive Pin Depth on Mating
Connectors. Measure the pin depth of the
connector that mates with the RF component,
before mating. Use an ANRITSU Pin Depth
Gauge (Figure 2, Table 1) or equivalent. Based on
RF components returned for repair, destructive
pin depth on mating connectors is the major cause
of failure in the field. When an RF component
connector is mated with a connector having a
destructive pin depth, damage will likely occur to
the RF component connector. (A destructive pin
depth has a center pin that is too long in respect
to the connector’s reference plane.)
The center pin on an RF component connector has a
precision tolerance measured in mils (1/1000 inch),
whereas connectors on test devices that mate with
RF components may not be precision types. Their
pins may not have the proper depth. They must be
measured before mating to ensure suitability. When
gauging pin depth, if the test device connector

measures out of tolerance in the “+” region, the
center pin is too long. Mating under this condition
will likely damage the RF component connector. On
the other hand, if the test device connector measures
out of tolerance in the “–” region, the center pin is too
short. While this will not cause any damage, it will
result in a poor connection and a consequent
degradation in performance.

Table 2.
b. Avoid Over Torquing Connectors. Over
torquing connectors is destructive; it may damage
the connector center pin. Never use pliers to
tighten connectors.
c. Avoid Mechanical Shock. RF components are
designed to withstand years of normal bench
handling. However, do not drop or otherwise treat
them roughly. They are laboratory-quality devices
and, like other such devices, require careful
handling.
d. Keep Power Divider Connectors Clean. The
precise geometry that makes the RF component’s
high performance possible can be easily disturbed
by dirt and other contamination adhering to
connector interfaces. When not in use, keep the
connectors covered. Refer to the next section for
cleaning instructions.
5. MAINTENANCE
ANRITSU recommends that no maintenance other
than cleaning be attempted by the customer. The
power divider should be returned to ANRITSU for
repair and/or service when needed.
The traditional method of cleaning K Connectors
with a cotton swab and alcohol can break the
connector pin on the precision connector. The cotton
swab has a larger diameter than the area between
the inner wall and the center pin of the power divider
connectors.
ANRITSU still recommends using a cotton swab;
however, you need to trim the swab before inserting
it into the connector.
A cotton swab must never be used to cleaning
V Connectors; use a pinch of cotton held with
fine-pointed tweezers.
Some precautions to follow when using the power
divider:
•Use either the finger saver that has been
provided with the power divider or use an
8 inch-pound torque wrench for V and
K connectors or a 12 inch-pound for
N connectors when connecting the power
divider to other devices. No other tools are
recommended.
•Always spin the coupling nut to tighten
connections. Spinning the connector body
causes premature wear to the connector
interface.
