INSTALLATION AND OVERVIEW
General Description
This section describes the installation and theory of operation of the block up converter.
ABC40UKA is powered by +36~+60 VDC via IF cable.
The block up converter can be used as a stand-alone unit or in a redundant configuration.
Specifications
Appendix 1 summarizes the specifications of the ABC40UKA BUC. For mechanical specifications, refer
to the outline drawing, Appendix 2.
General Considerations
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 and M&C
to the corresponding connectors of the block up converter.
The cylindrical connectors are labeled clearly and have different pin layouts. It is
impossible to incorrectly install the mating connectors.
