Diplexers

A diplexer is a passive (RF) filter component with 3 ports, which enables the sharing of a common antenna between two distinct frequency bands. This technology allows transmitters operating on different frequencies to use the same antenna and each band may both transmit and/or receive.

For all multiplexer devices there are two input ports that are multiplexed onto a third port. This allows the signals from the two input ports coexist on the output port without interfering with each other.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
