Description
OUTDOOR 868MHz CAVITY FILTER.
FEMALE MALE
1、Ultralow Inter Loss ≤1.0dB
2、Ultra High Out of Band Rejection
≥55dB@853MHz ≥55dB@880MHz
Why we need a high out band rejection
filter?
The first function of the filter is to filter out interference
signals. Therefore, the higher the out band rejection is,
the closer it is to the working frequency band, the better.
A filter without marking this parameter is no different from
transmission line（about zero insertion loss）……
About Connections
1、There is no difference between the two RF ports of the
filter. Both side can be connected to the antenna or
miner.
2、The filter is connected between the antenna and miner, or
between the antenna and extender.
The 868MHz Cavity Filter operates from 863-870MHz with a 7MHz bandpassand
usesfor Helium Network.
This component has ultra-low insertion loss and a good out-of-band suppression at
10MHz from a distance of side frequency. The 868MHz Cavity Filter features rugged
aluminum construction and is for use outdoors.
The 868MHz Cavity Filterhas N female connectors in both side.
