ZXHF5000
4:2 IF switch with integrated gain and control
Summary
The ZXHF5000 provides an integrated IF
solution for multiple output LNB and switch
box applications. The ZXHF5000 includes a 4
by 2 switch with 19dB of positive gain which
can be connected directly to the output of the
LNB or switch box eliminating the need for
cable drive amplifiers.
The ZXHF5000 includes all the control required
for voltage and tone based systems providing a
reliable and highly integrated solution.
