1.2 GHz 85/105 Diplex Filter is a complete diplex filter with 75 ohms at all ports. This filter isolates the forward and reverse bands so that the two signals can share the same coax transport. The reverse path frequencies pass through the low-pass filter which has a cutoff frequency of 85 MHz, and the forward path frequencies pass through the high-pass filter which has a cutoff frequency of 105 MHz. The high-pass filter works out to 1200 MHz. Each of these filters, together with additional filtering provided on the amplifier motherboards, has enough isolation to prevent the amplifier from oscillating. It also provides enough isolation so that there is no interference between the forward and reverse paths.
These accessories can be used for nodes, amplifiers, line extenders, etc.
