MAX3509 Evaluation Kit
General Description
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
the parallel port of a standard PC. Software (Windows
廬
95/98 and DOS
廬
) is included to facilitate this function. This
software allows the user to program both the gain and
transmit modes through a simple user interface.
Access to the device input and output is provided through
50鈩?SMA connectors. The input is matched to 50鈩? while
the output circuit includes a minimum-loss pad that
increases the load on the output transformer to 75鈩?nomi-
nal when using 50鈩?test equipment.
