PRODUCT DETAILS
Why do 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
cheating; Even if it should not be called a filter, it should be a
transmission line（about zero insertion loss）.....
FEATURES
1、Full bandwidth 915-928MHz2、Outdoor use IP67
3、Ultralow inter loss ≤1.0dB
4、Ultra high out-of-band Rejection
≥50dB@900MHz ≥50dB@943MHz
DESCRIPTION
The 922MHz Cavity Filter operates from 915-928MHz with a 13MHz bandpass and uses for Helium Network.
This component has ultra-low insertion loss and a good out-of-band suppression at 15MHz from a distance of side frequency. The 922MHz Cavity Filter features rugged aluminum construction and is for use outdoors.
The 922MHz Cavity Filter has N female connectors on both sides.

figure1：inter loss ＜1dB and out of band Rejection ＞55dB（very important）
figure2：return loss ＜-26dB
About Connections
1、There is no difference between the two RF ports of thefilter. Both sides can be connected to the antenna or miner.
2、The filter is connected between the antenna and the miner, or between the antenna and extender.
