Model:
DMPA 2200
Features
· 2100 MHz - 2300 MHz Broadband Amplifier
· High linearity PA provides 50 Watt output for broadcast of digital waveforms
· Fully protected against input overdrive, temperature and output load VSWR conditions
· Remote control and self monitoring via RS485 interface
· HPA Monitor GUI software available for local PC control via RS232 interface (CD included)
· Integrated AC/DC power supply
Description
The DMPA 2200 is designed to operate as a final amplification stage for a terrestrial S-Band transmitter or repeater system. It amplifies an input S-Band signal to a digital average output power level of 50 Watts, while maintaining its linear characteristics.
The DMPA 2200 architecture is based on a solid state design operating in Class A/AB linear mode over a frequency range of 2100 MHz to 2300 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 2200 incorporates an internal automatic self leveling loop to maintain constant gain over the life of the equipment. The automatic gain control circuit will compensate for gain variations caused by changes in temperature and device aging. Depending on the application, the amplifier could be configured to operate in ALC mode, maintaining a constant output power level.
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 2200 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.
