3.3.5.3. Crossband Splitter/Coupler 550/800MHz (07-004815)
The purpose of Crossband Splitter/Coupler (07-004815) is to split or combine RF signals from
different parts of the frequency spectrum.
It is a 3 port device comprising two filters, one a low pass, the other a high pass, connected to a
common input/output. The couplers are housed in a machined aluminium casing having a centre
screening wall between the filter sections and lid secured by screws at frequent intervals over its
perimeter to obtain a tight seal and to ensure linearity and stability of response.
