ABC40SKX is powered by +30~+60 VDC via MS connector.
It will amplify an input signal from an L-Band RF source up to a power level of 40 Watts (min) CW in Ku-
Band.
The block up converter can be used as a stand-alone unit or in a redundant configuration.
Specifications
Table 1 summarizes the specifications of the ABC40SKX BUC. For mechanical specifications, refer to the
outline drawing, Appendix 1.
GeneralConsiderations
The block up converter shall meet all specifications over full bandwidth and under all environmental conditions
when terminated with a load of VSWR at 1.5:1 unless otherwise specified. All RF specifications shall be met
within five minutes after applying power, except gain flatness, which shall be met after a warm-up period of ten
minutes. During the warm-up period, the block up converter shall not exhibit any alarm or require an RF mute
input signal to reset any alarm/fault latches.
Securing the Block Up Converter
Align the block up converter output waveguide flange with the mating flange of the antenna feeder waveguide.
Using the O-ring and hardware provided, connect the antenna feeder waveguide. Torque the flange screws to 16
inch-pounds (1.8 N-m). Attach the proper cables for waveguide for IF input, AC power and M&C if equipped

instructions.
SiteConsiderations
The BUC is designed to mount on the antenna. Locate and install the antenna according to instructions supplied
by the antenna manufacturer. Choose an area that is free of extraneous interference from motors and electrical
equipment and has a clear line of sight from the antenna to the satellite. Lightning arrestors should be used at
the site to protect personnel and equipment.
Preparation
MountingConsiderations:
Optional Mounting Brackets are available that will facilitate mounting for most antennas.
The ODU must be mounted such that:
- Sufficient support is afforded to the BUC, the LNB and the Power supply to minimize the effects of antenna
sway in strong winds.
- Air movement across the heat fins is possible.
- The length of the Power supply cables is taken into consideration in determining the mounting location of the
power supply.
Throughout installation and during any polarization, azimuth or elevation adjustment, ensure that cables and
waveguide are not crimped or pinched.

Functional Overview
General
This section describes the block up converter functions in detail. The functional overview explains the RF
amplification, monitor & control and power distribution.
IF/RF Conversion and Amplification
The IF Input requires a signal with a 10MHz reference, and 30-60 VDC power source. 2-4.5Amps nominal
enters the BUC by a coaxial cable, converted to Ku-Band by the BUC and goes through an internal isolator and
reject filter, which provides a good VSWR at the input. Under normal operation, the RF amplifier will amplify
the RF Input signal level up to a power level of 45.5 dBm or 40 Watts CW minimum.
To achieve the rated output power of the RF Amplifier, provide the necessary gain and low insertion loss. The
amplified signal is transmitted through the output waveguide section to a satellite up-link system.
Monitor and Control (optional)
The block up converter may have a RS-485 and RS-232 serial interface. With this option the block up converter
can communicate to the indoor unit or redundancy control block up converter via RS-485 or RS-232.
The control system can provide the following M&C functions:
 BUC Alarm (via RS-485/RS-232): when an input BUC within the block up converter system current
draw is below 0.3A, a BUC alarm signal will be transmitted via the RS-485/RS-232 serial interface.
 Mute Control (via RS-485/RS-232)
 Mute Control (via hardware line): TTL high level signal will mute a block up converter
 Output Power Monitoring: 20 dB dynamic range (via RS-485/RS-232)
 Base Plate Temperature Monitoring (via RS-485/RS-232)

Operation
It shall be performed by authorized personnel prior to maintenance and/or repair.
Procedure
Verify that the installation procedure described was completed. A complete physical check of the customer’s
system is suggested.
WARNING!!
The output power available at the output waveguide flange is extremely
hazardous. Under no circumstances should block up converter be operated
without the waveguide feed or a high power load attached. Do not operate
this equipment in the presence of flammable gases or fumes. Failure to
observe this precaution will result in personal injury. Safe and careful
installation of this block up converter will eliminate the possibility of
accidents and provide years of top performance.
Verify the antenna feed waveguide connection is properly done before the block up converter is energized.
NOTE
The block up converter can withstand any source or load VSWR. However,
the block up converter will meet all specification requirements only if the
source/load VSWR is sufficient. Normal operation is not possible if the
antenna feeder VSWR is greater than 1.5:1.
Turn ON the power and allow a warm up period of twenty minutes before operating the block up converter.
This will assure stable gain and power. The block up converter can function with a coupler when a direct
measurement of the output power is made.
