Overview
The AWMA-C series are the outdoor solid-state power amplifiers
(SSPAs), operating in C-Band frequency range. The amplifier is an
integrated unit, complete with power supply and cooling system.
Intended for outdoor operation, the AWMA-3000C is weatherproof.
Built-in microprocessor controller provides the capability for serial
port interfaces (RS485, RS232) for remote monitoring and control.
Advantech’s SSPAs set the industry standard for linearity and
operating efficiency. Built-in design features and assembly methods
incorporated with efficient combining techniques result in the
trouble-free operation of the amplifier.
Application
The SSPAs are designed for C-Band satellite up-link applications.
They are mounted outdoors, near the hub of an antenna. The
AWMA-C series are available in output power from 20W to 1000W.
For higher power Advantech provides phase-combined systems.
Other SSPAs are available for operation at other satellite frequency
bands. With all the features of the AWMA-C, Advantech also offers a
built-in converter.
Redundancy
With the addition of the appropriate waveguide and switch kit, the
AWMA-3000C amplifiers can be easily converted for the operation
in 1:1 redundant configuration with full remote Monitor and Control
capability of the redundant system via serial interface. A single
Monitor and Control interface is required to manage redundant
system.
