Analogue transmissionformats are supported as well as digital transmissionformats. For many years, these devices have beenused worldwide for fixed satellite earth stations,satellite news gathering (SNG) vehicles <strong>and</strong> othermobile or portable applications. The up-<strong>and</strong> downconvertershave been produced more than 1200 timesso far <strong>and</strong> customers worldwide appreciate theirreliability <strong>and</strong> high level of quality.4th Generation – still betterThe 4 th generation, based on our experience <strong>and</strong> skill,is still better. The synthesizer <strong>and</strong> oscillator portion inevery satellite converter is the most importantcomponent because it decides the converter'sreliability. For many years WORK Microwave hasbeen developing <strong>and</strong> manufacturing highsophisticated microwave oscillators <strong>and</strong> synthesizers,which are used in our converter series as well. Thenew design allows us to reduce the number ofcomponents by more than 30%. In addition, significantimprovements have been made on circuit design.This design results in an AC power consumption oftypically 35 VA / 23 W. This leads to an even higherreliability <strong>and</strong> longer life time.S-, C-, X-, Ku-, K <strong>and</strong> Ka-B<strong>and</strong> coverageThe satellite converter series cover the satellitefrequency b<strong>and</strong>s S-, C-, X-, Ku-, K- <strong>and</strong> Ka-B<strong>and</strong>. Theconverters support the st<strong>and</strong>ard IF-frequency b<strong>and</strong>s70 ± 20 MHz <strong>and</strong>/or 140 ± 40 MHz. The conversion isperformed without spectral inversion. Theupconverters offer an increased power output(P 1dB ≥ +10 dBm) in all versions. The units areavailable as single b<strong>and</strong>, dual b<strong>and</strong> or as triple b<strong>and</strong>converters (see also next page under “Specials <strong>and</strong>OEM products).High signal integrityThe extreme low phase noise of the oscillatorsguarantees an excellent signal quality. Low spuriousemissions allow our customers to use the convertersalso in the environments with dem<strong>and</strong>ingrequirements, such as high power video uplinks.Sophisticated temperature compensation guaranteesthe stability over a very wide temperature range.Housing optionsThe converters normally are delivered without fans<strong>and</strong> can be operated in environments, where atminimum 1 RU space for natural ventilation isavailable above each unit. This eliminates the fan aspotential point of failure. For rack installations withoutany space in between the units a fan within theconverter unit is recommended, which forces anairflow from the right side to left side of the units.2012-09-173
