To reduce insertion loss(use many RF
adapters ), improve the sensitivity of the
system and reduce noise at the same
time, acasom has developed a new
filter , Type A for 915MHz.
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
cheating;Even it should not be called a filter, it should be a
transmission line(about zero insertion loss)......

The 915MHz Cavity Filter operates from 902-928MHz with a 26MHz bandpass and uses for Helium Network.
This component has ultra-low insertion loss 1.0dB and a good out-of-band suppression 60dB at 10MHz from
a distance of side frequency.
The 915MHz Cavity Filter features rugged aluminum construction and is for use indoors. The 915MHz Cavity
Filter has SMA female connectors in both side.
