SAFETY
This Unit contains delicate
electronics, electrical components
and high radiated RF power.
Follow all safety precautions in
this section when the Unit is in
operation.
Carefully read and follow all
safety, use, and operating
instructions before operating the
Unit. Retain these instructions for
future reference.
This section includes:
•Safety considerations for use of
the Unit.

Warning: High Power RF Hazard
Do not operate unless the RF output waveguide flange is
properly connected to the rest of the system or to a high power
load. The unit emits high power RF energy which could
be harmful to the human body.
When operating the equipment, never place personnel or any
object in front of or near the output waveguide opening.
Caution: Electrostatic Sensitive Devices
Be aware that there are devices in the Unit that are easily
damaged by ESD. Take standard ESD precautions when
handling the Unit.
When operating the Unit, observe these precautions:
Follow the connection
procedure described in this
manual in Section 4,
entitled “Install the Unit”.
Do not apply power to the Unit until
the Unit is appropriately connected to
the feed and antenna system or a high
power load. The Unit radiates
high energy RF.
Avoid Water and Moisture
on Connectors
The IF input, Power, M&C connections
should be tightly connected and sealed
against outside moisture using good
commercial practice and UV-rated
materials. Care should be taken on
the installation of an “O” ring for the
WR28 waveguide connection to
prevent contaminants from entering
the interface and to avoid pinching of
the gasket.
!

December 2007 Page 10 90-005-0003 Rev X01
50 Watt Ka Feedmount BUC User Manual
Provide Adequate Ventilation Since the Unit uses forced air
convection for cooling, it relies on
proper ventilation to ensure reliable
operation. The Unit draws air in
from the front side (face with
connectors on it) and exhausts air
to the back side.
THE VENTILATION MUST NOT
BE BLOCKED
To avoid overheating and ensure
that the ventilation slots are not
blocked, place the Unit at least 2
inches from any object that could
obstruct air flow.
If the Unit is placed in a closed
area, such as a building or radome,
ensure that proper ventilation is
provided and that the air
temperature does not exceed the
maximum rated temperature.
Use the Correct Power Source
To prevent damage to the Unit,
ensure that the applied AC power is
within the range of 90-264VAC.
Route Power Cords Safely Route power cords so that they are
not walked on or pinched. Pay
particular attention to cords and
connections at the plugs,
receptacles, and the point where
they exit from the Unit and attach
to other equipment. Do not place
any items on or against power
cords.

50 Watt Ka Feedmount BUC User Manual
Protect Against Lightning and
Power Surges
To protect against voltage surges
and built-up static charges, install
the Unit with appropriate grounding
methods in compliance with
grounding standards for electrical
and radio equipment according to
the electrical codes in the country of
installation.
To ensure continuous and
undisturbed unit operation from
primary power line anomalies, use
an Uninterruptible Power Source
(UPS) with your Unit.
Do not penetrate the Unit Touching internal parts in the Unit
is dangerous to both you and the
Unit. Never put any object through
slots or openings, as this could
result in touching dangerous
voltage points, short-circuiting
parts, electric shock, fire or electro-
static discharge (ESD). If an object
were to fall into the Unit, unplug the
unit, as serious damage could occur
to the unit.

SYSTEM DESCRIPTION
Wavestream’s patented Spatial Power
Advantage™ delivers RF power in a
small and light package. Our
patented technology delivers the
highest efficiency in the industry
resulting in significantly streamlined
thermal designs and high MTBF.
This section includes:
•A brief primer on Wavestream’s
unique spatial power combining
technology.
•Interface descriptions including
pin out and mating connector
information
•For more information visit
Wavestream’s website:

SPATIAL POWER COMBINING
How Grid Amplifiers™ Work
The spatially power combined Grid Amplifier employs a fundamentally different
technique for combining the outputs of the transistors. Rather than combining in
multiple stages and increasing loss and size with each combining stage, all
transistor outputs are combined in a single stage, minimizing the loss and size of
the combining network. Many amplifying elements are used to synchronously
amplify the input signal, and their outputs are combined in free space for very high
combining efficiency.

The PowerStream Grid Amplifier is powered by Wavestream’s Grid Amplifier chip
which consists of an array of several hundred transistors which together form an in-
waveguide amplifier as shown in the diagram below:
PowerStream™ Grid Amplifier™ using Patented Spatial Power Combining
Wavestream’s Grid Amplifier architecture provides significant advantages over
traditional SSPAs which use microstrip or waveguide combining. All the MMIC
amplifier outputs are combined in a single stage of combining in air, making the
amplifier highly efficient. Furthermore the signal never traverses a bond wire,
removing a key single point of failure found in traditional amplifiers.

INTERFACES
The Unit has the following interfaces:
“IF /REF IN”CONNECTOR (J1)
The “IF / REF IN” Connector is a Type N female connector.
Type N Connector
The Unit requires that the L-Band (1000-2000MHz) Input and a 10MHz
reference are multiplexed into the “IF IN / REF IN” Connector. Most
modems are configured to provide the required multiplexed signal and
reference. This multiplexing can be performed using a bias tee and a
separate reference source if unavailable from the modem.
“RF OUT”CONNECTOR (J2)
The “RF OUT” Connector is a WR28 waveguide flange.
WR28 flange
When operating, the Unit will output up to 50 Watts of RF power at Ka-
Band (30.0-31.0GHz). To make a water-tight connection, the mating
WR28 flange should have an O-Ring groove and the appropriate O-Ring
ought to be inserted prior to mating this interface.
“120VAC IN”CONNECTOR (J3)
The “120VAC IN” Connector is a 3-Pin Circular Connector. This is an ITT
Cannon part with part number CB7-16-10PS. Its mating connector (part
number CB6E16-10SS) has been supplied with the Unit.
ITT Cannon P/N: CB7-16-10PS
The Unit is powered from this connector. At peak output power, the Unit
will not draw more than 6.5 Amps.

GROUND STUD
Located between connectors J3 and J4 is a ground stud which is screwed
into the main body of the Unit. This should be used to ground the Unit to
the rest of the system.
MOUNTING INTERFACE
•The Unit is designed to mount to a plate via the 2 sets of 3 ¼-20 bolt
holes located on each side of the Unit. The plate should be designed to
be capable of carrying the weight of the Unit. That plate is the typically
attached to a feed arm or other platform. No conductive cooling is
assumed. Therefore, the function of the Unit’s mounting interface is
simply to enable meeting the system vibration and shock requirements.

ADDITIONAL INFORMATION
The Fans: The Unit cools itself with fans. These fans are weatherized to
handle an extreme environment that includes heavy spray. They will
shut off when the temperature of the Unit is below 10°C. The fans are
the only serviceable part in the Unit. To replace the fan assembly, see
Section 7.
Cable Construction: If the M&C cable is greater than 6 feet, it is
recommended that multi-conductor shielded cable be used to reduce
noise pickup. Shield should be connected to the case. The Ground Stud
on the chassis can be used for this purpose.
