Chapter 2 System Description
2.3.17.2 High Band Transmit Output Filter (Waveguide)
T
he HB transmit output filter is a waveguide, dual mode band pass filter which provides
attenuation of the out-of-band emissions generated by the HB HPA. The attenuation is to
comply with TRS-DRU System-SPEC-00-10-200, Rev 1.2, DRU System RF Output Filter
Network Specification.
2.3.17.3 Low Band Transmit Output Filter (Waveguide)
T
h
e LB transmit output filter is a waveguide, dual mode band pass filter, which provides
attenuation of the out-of-band emissions generated by the LB HPA. The attenuation is to
comply with TRS-DRU System-SPEC-00-10-200, Rev 1.2, DRU System RF Output Filter
Network Specification.
2.3.17.4 Low Band Diversity Transmit Output Filter (Waveguide)
In an Indep
e
ndent DRU, the LBD transmit output filter is a waveguide, dual mode band pass
filter, which provides attenuation of the out-of-band emissions generated by the LBE LBD
output. The attenuation is to comply with TRS-DRU System-SPEC-00-10-200, Rev 1.2, DRU
System RF Output Filter Network Specification.
2.3.17.5 Low Band Diversity Transmit Output
Filter
(Dielectric Resonator)
In a Combined DRU, the LBD transmit output filter is a dielectric resonator band pass filter,
which provides attenuation of the out-of-band emissions generated by the LBE LBD output.
The attenuation is to comply with TRS-DRU System-SPEC-00-10-200, Rev 1.2, DRU System
RF Output Filter Network Specification.
