PowerMax Scalable Systems

Paradise Datacom reveals its next step in fully modular high power amplifier systems with its PowerMax Scalable SSPA Systems.

The PowerMax system maintains complete parallel redundancy down to the embedded control level. Therefore the loss of an entire HPA chassis will not interrupt remote communications with the system. Remote communications can be either RS485 or Ethernet. The system will automatically correct its gain level in the event of one or more HPA chassis failures.

The sophisticated system monitor and control allows the system to be locally or remotely operated as if it were a "single" chassis amplifier. The system control maintains a hierarchical management that allows the operator to interface to a single chassis of the multi-module array.

Another feature unique to Paradise Datacom's PowerMax is the introduction of "true rms" output power measurement. Unlike other amplifier systems that utilize diode detection schemes, the PowerMax reports the true rms output power of the system independent of the number of carriers and modulation schemes.

Proprietary waveguide combining techniques are employed so that maximum power combining efficiency is optimized within the operating frequency band.

Because the system power combining is purely passive and no switching is used, there is never an interruption in RF output power. The PowerMax system is typically used as a "self-redundant" system. The output power is sized such that the loss of (1) RF module’s power will still allow the system to maintain its minimum required output power. This type of system architecture is described as n+1 redundant. The system can be configured with any number of modules but best overall efficiency is obtained with the popular binary combinations of 4, 8, or 16 modules.

The following power levels are available:
