    NTRODUCTION 1.1 Overview This manual describes the installation and operation (I&O) procedures of CPI’s Indoor Units (IDU) 100W, 125W, and 225W SSPA (Solid State Power Amplifier) for service in satellite earth stations. Technical maintenance for repair and troubleshooting is covered in the Service Manual.

  • Page 8: General Description

    NTRODUCTION 1.2 General Description The Indoor SSPA is a self-contained unit consisting of a power supply, a solid state brick containing an array of Gallium Arsenide (GaAs) FET devices, a microprocessor driven controller, and cooling system. Typical model weight and dimensions are shown in table 1-2. Table 1-2.

The entry event log puts a time and date stamp on every entry. After 2000 entries the next entry will overwrite the oldest one.

  • Page 11: Automatic Power Compensation

    NTRODUCTION 1.3.15 Automatic Power Compensation The amplifier can be set to achieve a constant output power using the variable gain attenuator automatically. The attenuator will compensate for input drive level changes as well as temperature changes. 1.3.16 Variable Gain Attenuation The SSPA overall gain can be adjusted up to 23dB in 0.1dB steps.

    SSPA with an L-Band input frequency of 950 to 1825 MHz. The BUC converts the L-Band input frequency to the output frequency of the SSPA. CPI’s BUCs use DRO (Dielectric Resonant Oscillators) that can operate independently or be phase locked to a high-stability reference. The reference signal is brought into the amplifier by multiplexing the reference onto the cable carrying the input signals, so that no extra cables are required.

  • Page 13: Transient Surge Suppression

    NTRODUCTION The main RF voltage will be supplied using all available modules to a maximum of four total. The extra power supplies are hot swappable (able to be changed while the unit is operating). At least one module is required to operate the amplifier. The operator can observe the status of the power supply using the front panel display, which will update with each module insertion/extraction.

  • Page 14: Ethernet Lan Interface

    NTRODUCTION 1.4.6 Ethernet LAN Interface The Ethernet port allows the SSPA to be monitored and controlled from anywhere that the local area network (LAN) can reach. 1.4.7 Redundant/Phase Combined Switch System The redundant switch system is detailed in the dedicated manual that accompanies the switch. The available switch systems include redundant configurations as well as power/phase combined systems.
