companies listed here can supply your needs for any type of filter. They provide not only a stock of off-the-shelf
models, but can also design and manufacture custom models for meeting specialty selectivity, group delay, insertion
loss, form factor, power handling, or other unique parameters.
Everyone is clear on what a filter is, but there
exists a lot of confusion over what is the difference between a duplexer and a diplexer. As you might expect, there
are a lot of opinions - even between manufacturers. Traditionally, duplex communications implies the ability to
transmit (Tx) and receive (Rx) on the same channel simultaneously. doing so requires a means of separating the transmit
and receive paths in a manner rendering them independent of each other, i.e., isolation. Thus, a duplexer is used.
One method is to use a circulator for routing signals from the transmitter to the antenna while routing singles
from the antenna to the receiver. If the Tx and Rx operate at different frequencies, the job can be accomplished
by a set of filters with a common feed point. A diplexer is usually thought of as a set of filters, again with a
common feed point, that is used to combine or split signals travelling to or from an antenna, respectively, while
providing isolation between the two independent paths. If more than two independent paths are required, the name
for both usually changes to a common term: multiplexer.
