RF / Microwave Filters, Diplexers & Duplexers
Manufacturers & Services
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
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:

Coupling Matrix Synthesis™ software facilitates synthesis of N+2 coupling matrices for
Chebyshev bandpass filtering functions, with arbitrary finite-position transmission
zeroes. The software also facilitates coupling matrix synthesis through topology matrix
definition. It gives a fast and accurate overview of insertion loss, isolation, group
delay and coupling coefficients versus filter order, return loss and transmission zero
positions. The software allows placement of complex transmission zeroes, which opens
up for group delay shaping and analysis.
