MAX3509 Evaluation Kit
General Description
Features
The MAX3509 evaluation kit (EV kit) simplifies evaluation of
the MAX3509 CATV upstream amplifier. The kit includes a
serial data interface, which can be programmed through
o Single-Supply Operation
o Output Level Range from < 12dBmV to
67dBmV (QPSK)
o Gain Programmable in 1dB Steps via Software
o Transmit-Disable Mode
®
the parallel port of a standard PC. Software (Windows
®
95/98 and DOS ) is included to facilitate this function. This
software allows the user to program both the gain and
transmit modes through a simple user interface.
o Shutdown Mode
Access to the device input and output is provided through
50Ω SMA connectors. The input is matched to 50Ω, while
the output circuit includes a minimum-loss pad that
increases the load on the output transformer to 75Ω nomi-
nal when using 50Ω test equipment.
o Control Software Included
o Fully Assembled and Tested Surface-Mount
Board
