2. GENERAL INFORMATION
2.1 INTRODUCTION
This manual contains information that describes installation, operation and maintenance
procedures for the 40 W Ku-Band hub-mount (outdoor) Solid State Power Block Up-Converter
model SSPB-K40-CSE. Because specialized training is required for some phases of installation
and operation, certain parts of this manual are directed only to trained personnel. Warnings
appear at the appropriate points to caution all users of potential RF and high-voltage hazards.
For a safe and versatile operation, please read the information carefully BEFORE using the
equipment.
ADVANTECH Advanced Microwave Technologies, Inc. has prepared this manual for use as a

2.2 DESCRIPTION
The SSPB-K40-CSE is a 40 W Ku-Band hub-mount (outdoor) Solid State Power Block Up-
Converter (SSPB). The entire SSPB is self-contained and is intended for mounting near the hub of
the antenna. It incorporates DC main power supply and forced air-cooling system, see Figure 1:
Product Outline (page 12). The block diagram of the SSPB is shown in Figure 2: Block Diagram
(page 13) and various connectors are shown in Figure 3: Connectors (page 16).
2.2.1 POWER SUPPLY
There is one power supply in this unit. This power supply provides a +12 VDC high current and
– 9 VDC and + 15 VDC low current to the High Power Amplifier (HPA) as well as 48 VDC for
the cooling fan.
The power supply is configured for operation from 90 to 132 VAC or 180 to 264 VAC
(autoranging), single phase, 47-63 Hz.
The fan is configured for 48 VDC operation. This voltage may vary between 11 VDC and
64 VDC, depending on the temperature sensed at the hot spot of the amplifier and thus
allowing for a variable, temperature dependent, rotation speed of the cooling fan.
The overall power consumption, at rated RF output power, is 650 W.
