Hi,

I am currently updating a cable tv hardware design.  The design at present
uses a resistive pad matching device from mini circuits.  This is necessary
to match the incoming 75ohm CATV cable to the 50ohm electronics used in the
design.  This part is expensive and has an insertion loss of 5.7dB and I'm
pretty sure this type of impedance match can be performed using a wide band
RF transformer such as those manufactured by macom (http://www.macom.com).
In particular I'm considering using the ETC1.5-4 which has 1.5:1 impedance
ratio and is an unbalanced to unbalanced transformer.  However before I
proceed I really would appreciate any thoughts the list might have on this
topic as I am only new to this game (3 months) and I don't want to make the
wrong decision.


Thanks in advance,
Damien.
