Tuning (Set) Screws

Here are a few companies that provide tuning (set) screws for cavity filters & oscillators:

Set Screw & Mfg. | Bolt Depot | McMaster-Carr | Grainger | MSC Direct | eBay (a great source) | Home Depot | Lowes

The 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.
