Our Semi-Custom Products:
“Almost Off the Shelf”
The products offered on AMCrf.com are either available from stock or in a few days after your order. However
it's important to remember that the products you see on our site are popular models used in specific
applications, frequencies, and configurations. However, they’re just examples of the products many of whose
specifications we can quickly modify. That is, you should think of them as “almost off-the-shelf “as we can
turn them around quickly and in most cases without any NRE.
For example, key parameters of most
filters can be modified very quickly, such as center frequency, bandwidth, rejection points, and connectors
such as BNC, SMA, Type-N, TNC, SMC, etc. Even though our ceramic filters are designed for surface mounting,
they can be placed in a connectorized enclosure and still retain their superb electrical characteristics very
Need it weatherized? No
Of all the types of filters we manufacture, cavity bandpass filters are the most likely to be used
outdoors or within closed areas that are not totally sealed from the ravages of the environment. This is
typical when they’re used to remedy interference conditions that did not exist during installation or when
modifications are made to accommodate new wireless networks, many times at the top of the tower. As we are
almost continuously manufacturing cavity filters for wireless, satellite communications, and other systems
that must be protected against hostile environments, specifying one of our standard products for outdoor
applications will almost never significantly increase delivery time.
In addition, while products for
defense applications can often require significant “hi-rel” testing, other MIL specs can be met by standard
products with modifications that we can make quite quickly. This is because Anatech Electronics has been
manufacturing filters and other products for defense applications for decades and our in-house capabilities
make this possible.
Filters are not the only products that can be modified in many ways to become semi-custom models, and various
specifications and physical conditions to power dividers, directional couplers, and other products can be made
quickly as well.
