The PA700-T740_746 is a solid state, fixed gain power amplifier for operation in the US 700 MHz frequency
band. Advanced LDMOS design permits the PA700 to operate with high level digital signals such as 64QAM,
DVB-T or 8-VSB DTV. The PA700 can be operated on a stand-alone basis or controlled via SNMP or front
panel display when serially connected to a UCD4940. Together, the PA700 and UCD4940 offer a complete
solution for up-conversion, down-conversion and high linearity amplification in a rack mount configuration
requiring only 4U of rack space*. This advanced, cost effective power amplifier offers high performance and
flexibility in a space-efficient design. The unit is state of the art in terms of easy assembly, reliability and
performance.
The PA700 is factory configured and calibrated for operation at a specific band.
