WARNINGS & CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This unit may contain hazardous voltages. Before removing the unit from the rack remove all supplies
and disconnect user I/O signals.
If the unit has removable modules, unused slots in the chassis must be populated with blanking
panels to prevent access to user I/O signals that may be present. Blanking panels are available to
order from Pickering. If the product is not used in this manner for example by using an extender card
then additional care must be taken to avoid contact with exposed signals.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This unit must not be used for the switching of Mains Circuits. For the switching of voltages up to the
unit’s full specication, Secondary Circuit power supplies and the Device Under Test must be fully
isolated from the Mains Circuit and the safety earth.
The chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to the installation section of this manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classied as Overvoltage
Category II up to 300V. Separation between the Secondary Circuit and Mains Circuit is achieved
by a transformer in which the primary windings are separated from the secondary windings by
reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.

LXI 50Ω 4 CHANNEL MICROWAVE MULTIPLEXER 60-802
WARNING
Only the correct SMA connector series should be mated with this unit. The 40GHz versions
(60-802-4xx) uses SMA-2.9 connectors and the user should only mate the correct type to the
unit, failure to do so may result in damage to the connector.
Also, it is important that the SMA connector’s nut is properly tightened to the correct torque
with a 5/16 inch wrench. This should be 3-5 in·lbs (0.3 to 0.6 N·m) for brass, and 7-10 in·lbs
(0.8–1.1 N·m) for stainless steel connectors.

SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O
signals (refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
the combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the
chassis and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on
the front of the unit.
WARNING - RACK MOUNTING
If it is required to t this unit into a 19 inch rack, its weight must be
supported by side brackets, runners or a suitable equipment shelf.
The xing holes in the front panel anges are designed only for
securing the device in the rack and must NOT be used to support
the weight of the whole device.
Please refer to Appendix A for the procedure for tting the
supplied anges to either side of the front panel.
!
HIGH VOLTAGE SAFETY WARNING
THIS UNIT IS CAPABLE OF SWITCHING VOLTAGES AND CURRENTS THAT CAN
CAUSE SERIOUS INJURIES. IN APPLICATIONS INVOLVING HIGH VOLTAGES IT
IS STRONGLY RECOMMENDED THAT UNUSED CONNECTORS ARE CAPPED
TO PREVENT ACCIDENTAL CONTACT WHILE IN USE. SYSTEM INTEGRATORS
AND USERS SHOULD CONNECT TO THE FRONT PANEL CONNECTORS WITH
CONNECTORS OR CABLE ASSEMBLIES THAT ENSURE OPERATORS WILL NOT
INADVERTENTLY COME IN CONTACT WITH HIGH VOLTAGES.

Schematic Diagram for the 60-802
Microwave MUX - up to 16 Multiplexer
Modules can be supported
The 60-802 Microwave Multiplexer is suitable for switching
50 Ω signals up to 40 GHz. With up to 16 banks of 4 channels
it is ideal for constructing complex microwave switching
systems for many applications. Connection is by front panel
mounted SMA or SMA-2.9 connectors.
The multiplexer have an extremely high level of
performance with low VSWR, very high isolation, low loss
and high power handling. It is ideal for switching 50 Ω
systems for HF up to microwave frequencies. It occupies
1U (1-8 bank versions) or 2U (9-16 bank versions) of rack
space, providing a compact switching solution. Multiplexers
can be user connected to create customized switching
systems which include both multiplexer and matrix
arrangements.
Controlling the Multiplexer
The 60-802 is controlled through an LXI interface based on
Ethernet 1000Base-T. This provides a quick and easy method
of installing the 60-802 in a system and a simple way of
controlling the unit from a remote location through its API
or built in soft front panel. The ability to control the unit at a
distance aids the testing of systems without the need for a
physical presence.
Easy Repair
To allow fast in field repair, unterminated relays may be
individually replaced without removing the covers from the
chassis or the chassis from the host rack.
Other Microwave Switching Configurations
We are able to offer other microwave switching solutions, if
you have a custom requirement for switching please contact
your local Pickering Interfaces sales representative.

FUNCTIONAL DESCRIPTION
Figure 2-1. Block Diagram for the 60-802 Microwave Multiplexer (8-Bank version)
The 60-802 is a microwave multiplexer with up to 16 banks under the control of an LXI interface designed for the
routing of signals with frequencies up to 40GHz. Each multiplexer can be used in isolation, cascaded to form larger
multiplexers, or linked together to form a microwave matrix. A block diagram for an 8-bank, 4-channel multiplexer
is shown in Figure 2-1
Switch setting information for the multiplexer is sent from the Embedded Processor to the Relay Driver PCBs via
a Bridge circuit. The Relay Driver board’s data ports are interconnected in a daisy chain and are controlled with a
serial data stream from the Bridge board. Programming information for the processor is sent to the unit via the LAN
interface from a remote computer using the unit’s unique Ethernet address. Programming documentation for the
unit as well as data for Pickering’s other LXI compatible switching products is stored in the embedded processor
and can be downloaded over the LAN interface. LXI Status LEDs on the front of the chassis indicate the condition
of the unit and the LAN connection.

SECTION 2 - TECHNICAL DESCRIPTION
LXI 50Ω 4 CHANNEL MICROWAVE MULTIPLEXER 60-802
CONFIGURATION AS A MATRIX
As well as being able to be cascaded to form larger multiplexers, the 60-802 can be congured as a microwave matrix.
For example, eight 4-way microwave multiplexers can be interconnected to create a 4x4 matrix, with the common
of each multiplexer forming the X and Y connections. The four channels of each X multiplexer are connected to one
channel of each of the four Y multiplexers (see Figure 2-2). This allows any X signal to be connected to any Y signal
with a maximum of four “cross-points” being active at any one time.
