The DMPA 2600 is designed to operate as a final amplification stage for a terrestrial MMDS-Band transmitter or repeater system. It amplifies an input MMDS-Band signal to a digital average output power level of 50 Watts, while maintaining its linear characteristics.
The DMPA 2600 architecture is an LDMOS based solid state design operating in Class A/AB linear mode over a frequency range of 2500 MHz to 2700 MHz. The amplifier is fully protected against input overdrive, overheating and output load VSWR conditions. The protection circuits are all self correction, allowing the amplifier to
be restored to its normal operating state upon removal of the fault condition.
The DMPA 2600 incorporates an internal automatic self leveling loop to maintain a constant output over the life of the equipment. The automatic level control (ALC) circuit will compensate for the input signal level variations and the gain variations caused by changes in temperature as well as for the gain change due to devices aging. Depending on the application, the amplifier can be configured to operate in AGC mode, maintaining a constant gain value.
The amplifier’s operational parameters are monitored and controlled
by an embedded system controller that can be accessed from the RS232 interface using the GUI software provided.
The DMPA 2600 is a field replaceable system component that includes an integrated AC/DC power supply and is designed for indoor installation.
All of the amplifier’s components are enclosed in a standard 19” rack mount chassis, occupying only “2RU” of cabinet space.
The amplifier is forced air cooled using four high performance fans, which are installed on the amplifier enclosure front panel.
