Ka-BAND BLOCK UP CONVERTER (BUC)
ACTX-Ka Medium Power Series (10 & 20W)
|
|
|
ACTX-Ka series are a family of outdoor RF Block-Up Converters (BUC), designed for Ka-band satellite communication systems. ACTX-Ka BUCs are integrated units with power supply, phase locked oscillator, power amplifier and frequency converter.
ACTX-Ka series BUCs have been tested and calibrated between -20șC and +55șC, providing very good gain stability with temperature. They also include a temperature alarm and power supply shutdown to protect the amplifier from permanent damages in high temperature conditions. Standard communication is via serial port (RS232/RS485), but TCP/IP and SNMP could be selected as options. |
